What is the range of the function f(x) = 2x + 4 when the domain is {-2, 0, 3}?

Answers

Answer 1

Answer: range = {0, 4, 10}

Step-by-step explanation:

Range means y which means f(x)

so we just have to plug in the domains(x) into the equation one at a time

f(-2) = 2(-2) + 4 = 0

f(0) = 2(0) + 4 = 4

f(3) = 2(3) + 4 = 10

those would be the range.. hope I was fast enough haha

Answer 2

Answer:

y = 3x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 12 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes , then

y = 3x + c ← is the partial equation

To find c substitute (1, - 2 ) into the partial equation

- 2 = 3 + c ⇒ c = - 2 - 3 = - 5

y = 3x - 5 ← equation of parallel line

A) x=3 and b) x= 9/3

Answer:

x = 3

x = 4.5

Step-by-step explanation:

A) 2(5x - 3) = 24

5x - 3 = 12 (divide both sides by 2)

5x = 15 (add 3 to both sides)

x = 3 (divide both sides by 5)

B) 5(2x + 1) = 50

2x + 1 = 10 (divide both sides by 5)

2x = 9 (take 1 away from both sides)

x = 4.5 (divide each side by 2)
