A quadratic function is defined by f(x) = x2 – 8x – 4. Which expression also defines f
and best reveals the maximum or minimum of the
function?
(x– 4)2 + 20
x(x – 8)-4
(x– 4)2 + 12
(x – 4)2 – 20

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. : )
