Evaluate the function if x=-3
f(x) =1/2x-1
A. -2.5
B. 0.5
C. -4
D. -1

A) -2.5

Step-by-step explanation:

You have to plug the x-value into the function.

f(x) = (1/2)x - 1

f(x) = 1/2(-3) - 1

f(x) = (-3/2) - 1

f(x) = -1.5-1

f(x) = -2.5

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. : )
