What is the axis of symmetry for f(x) = 2x − 8x + 8? (1 point) Select one: a. x = −2 b. x = −3 c. x = 3 d. x = 2
ExtremeBDS [4]

Answer:

x=2

Step-by-step explanation:

F(x) = 2x^2 - 8x +8

Axis of symmetry lies at the x coordinate of vertex

To find x coordinate of vertex use formula

x=\frac{-b}{2a}

from the given f(x) , a= 2 and b = -8

Plug in all the values

x=\frac{-(-8)}{2(2)}

x=\frac{8}{4}=2

x=2

So the axis of symmetry at x=2
