Answer:
C.
Step-by-step explanation:
A one to one function is a function in which an element in a domain is corresponding to the a single element in the range. That is, each element in the domain has exactly one image in the range.
To answer the question that say : What is a one-to-one function?
A function f is called a one-to-one function if it never takes on the same value twice.
Therefore the correct answer is option C.

distributive propertyaddition (subtraction) property of equalityadditive identity element (properties of real numbers)division property of equalitymultiplicative identity element (properties of real numbers)Step-by-step explanation:
A lot of math is about identifying and matching patterns. Often, the patterns have an associated vocabulary. It helps to learn the patterns and the associated words.

Pattern: a(b +c) ⇔ ab +ac . . . description: distributive property
Pattern: a = b ⇒ a +c = b +c . . . description: addition property of equality
Pattern: a = b ⇒ a/c = b/c . . . description: division property of equality
Patterns: a -a = 0; a + 0 = a . . . description: properties of the additive inverse and the additive identity element
Patterns: a×(1/a) = 1; a×1 = a . . . description: properties of the multiplicative inverse and the multiplicative identity element
__
When parentheses come or go, the distributive property is usually involved. In the second line, you need to recognize that -2(3y) = -6y and that -2(-7) = +14. The result on the left is from applying the distributive property to remove parentheses.
The third line differs from the second line in that -14 shows up on both sides of the equal sign. This is a clue that the addition (or subtraction) property of equality is involved.
The fourth line differs from the third in that +14-14 disappeared from the left side, and -4-14 was replaced with -18 on the right side. The sum of a number and its opposite is zero, a property of the additive inverse. The fact that -4-14 = -18 is a property of real numbers. (You have to decide the best drop-down choice for that line.)
The fifth line shows both sides of the equation divided by -6. The multiplication (division) property of equality lets you do that.
The last line shows a simplification of the previous one. Again, the properties of real numbers and of the multiplicative inverse are involved. (You have to decide the best drop-down choice for that line.)

It is 3 because if you plug the numbers into the formula (y2-y1/x2-x1) you get 3/1, which simplifies to 3.
Step-by-step explanation:
Well you have to do y2-y1/x2-x1

Find all solutions y(real and otherwise)to the equation
y^8+16=17y^4
Answer:
y=2, y=-2 y = 2i, y= -2i y = 1, y = -1 y = i, y = -i
Step-by-step explanation:
y^8+16=17y^4
Subtract 17 y^4 from each side
y^8 - 17 y^4+16=17y^4-17 y^4
y^8 - 17 y^4+16 =0
Let x = y^4
x^2 -17x + 16 =0
Factor
( x-16) ( x-1) =0
Using the zero product property
x-16 =0 x-1 =0
x=16 x=1
Replace x with y^4
y^4 = 16 y^4 = 1
y^4 -16 = 0 y^4 -1 =0
Replace y^2 with z
z^2 -16 =0 z^2 -1 = 0
( z-4) ( z+4) = 0 ( z-1) = 0 ( z+1) =0
z=4 z=-4 z=1 z=-1
Replace z with y^2
y^2 = 4 y^2 = -4 y^2 = 1 y^2 = -1
Taking the square root
y=2, y=-2 y = 2i, y= -2i y = 1, y = -1 y = i, y = -i
Express each of these system specifications using predicates, quantifiers, and logical connectives, if necessary.
a. At least one console must be accessible during every fault condition.
b. The e-mail address of every user can be retrieved whenever the archive contains at least one message sent by every user on the system.
c. For every security breach there is at least one mecha- nism that can detect that breach if and only if there is a process that has not been compromised.
d. There are at least two paths connecting every two dis- tinct endpoints on the network.
e. No one knows the password of every user on the sys- tem except for the system administrator, who knows all passwords.
The system specification with predicates, quantifiers, and logical connectives are:
a. ∃C(x) ∀F(y) such that if F(y) is true, C(x) is true.
b. ∀U(x) (∃M(y) if ∀U(z), ∃M(w) is true, then E(x) is true).
c. ∀B(x) (∃D(y) D(y) can detect B(x) ↔ (∃P(z) ¬P(z) is true)).
d. ∀E(x, y) (∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect
E(x, y)).
e. ∀U(x) (¬P(x) is true, except for the system administrator who knows all passwords: ∀U(y) P(y) if y is the system administrator).
We have,
a.
Let C(x) be the predicate "x is a console" and F(x) be the predicate "x is a fault condition".
The specification can be expressed as:
∀F(x) ∃C(y) such that if F(x) is true, C(y) is true.
b.
Let U(x) be the predicate "x is a user" and M(x) be the predicate "x is a message".
The specification can be expressed as:
∀U(x) ∃E(y) such that if ∀U(x), ∃M(z) is true, E(y) is true.
c.
Let B(x) be the predicate "x is a security breach", D(x) be the predicate "x is a detection mechanism", and P(x) be the predicate "x is a compromised process".
The specification can be expressed as:
∀B(x) ∃D(y) such that D(y) can detect B(x) if and only if ∃P(z) such that ¬P(z) is true.
d.
Let E(x, y) be the predicate "x and y are distinct endpoints" and P(x, y) be the predicate "x and y are connected by a path".
The specification can be expressed as:
∀E(x, y) ∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect E(x, y).
e.
Let U(x) be the predicate "x is a user" and P(x) be the predicate "x knows the password".
The specification can be expressed as:
∀U(x) ¬P(x) is true, except for the system administrator who knows all passwords, which can be expressed as:
∀U(x) (x is the system administrator → P(x)).
Thus,
The system specification with predicates, quantifiers, and logical connectives are:
a. ∃C(x) ∀F(y) such that if F(y) is true, C(x) is true.
b. ∀U(x) (∃M(y) if ∀U(z), ∃M(w) is true, then E(x) is true).
c. ∀B(x) (∃D(y) D(y) can detect B(x) ↔ (∃P(z) ¬P(z) is true)).
d. ∀E(x, y) (∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect
E(x, y)).
e. ∀U(x) (¬P(x) is true, except for the system administrator who knows all passwords: ∀U(y) P(y) if y is the system administrator).

Help HELP!
Thanks to the ones helping me I very much appreciate it so so much!
Answer:
We are given the function h(y) = 4|y + 2| - 3
So, to get the value of h(-8), we just have to replace the y in the equation with -8
In functions, the variable in the parentheses next to the name of the function is the variable we have to replace since the function is defined in the terms of that one variable. When you do more advanced questions, you will encounter functions with more than 1 variable
h(y) = 4 | y + 2 | - 3
replacing y with -8 to get the output in terms of -8
h(-8) = 4 | -8 + 2 | -3
h(-8) = (4 * 6) - 3
h(-8) = 24 - 3
h(-8) = 21

The answer is 3⁷ because when you are multiplying exponents with the same base, you keep the base and add the exponents. an example of this would be 4² x 4³. To simplify the expression you ignore the base, which is 4, and add the 2 and 3 to get 4⁵. So the answer to your question is 3⁷.
