Using the function f( x) = -3 x – 5, calculate f(-7).

f = 16

Step-by-step explanation:

just plug in -7 for x

so f(-7) = -3 (-7) -5

(apply -(-a)=a rule)

f=3 x 7 -5

f = 16

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
