for f(x) evaluate each of the following:
a. f(0)
b. f(6)
show all your work
Answers
Answer:
Step-by-step explanation:
a)
f(0) is just the function f(x) evaluated at 0, meaning we need to plug in 0 to the function.
What piece of this function should we plug 0 in? Well, because 0 is less than 5, plug it into the first piece.
so f(0) = 0 + 4 = 5
b)
By similar reasoning:
f(6) = 8
because 5 <= 6 < 7

How do you convert 3.2 (2 repeating) as a fraction?
Answers
Answer:
3+2/9 = 29/9
Step-by-step explanation:
examples:
4/9 = 0.444444
8/9 = 0.888888
3/9 = 0.3333333
7/9 = 0.777777
1/9 = 0.111111111
2/9 = 0.22222222
80/99 = 0.808080
67/99 = 0.6767676767
44/99 = 0.4444444
12/99 = 0.1212121212
345/999 = 0.345345345
i think you get the point.
so we know 2/9 = 0.22222, so now just add a 3:
3+ 2/9 = 27/9 + 2/9 = 29/9
When g ( t ) = 3 t 2 + 2 t + 1 , evaluate g ( − 4 )
Answers
Answer:
Just substitue every 't' with -4
Step-by-step explanation:
g(-4) = 3*(-4)*(-4) + 2*(-4) + 1
g(-4) = 64-8+1
g(-4) = 57
Answer:
g(-4) is 41
Step-by-step explanation:
[tex]g(t) = 3 {t}^{2} + 2t + 1[/tex]
when t is -4, substitute -4 in place of t:
[tex]g( - 4) = 3 {( - 4)}^{2} + 2( - 4) + 1 \\ g( - 4) = 48 - 8 + 1 \\ g( - 4) = 41[/tex]

Answers
Answer:
it is detailed solution. please mark brainlest.
Thank you have a nice day
The equation of the absolute function that has the solutions of -1 and 5 will be |x - 2| = 3.
What is an absolute function?The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x |
The solutions of the absolute function are -1 and 5. Then the equation of the absolute function will be
x = -1, 5
Subtract -2 from both sides, then we have
x - 2 = -3, 3
Then apply Mode on both sides, then the equation will be
|x - 2| = 3
The equation of the absolute function that has the solutions of -1 and 5 will be |x - 2| = 3.
