Hello,

Answer x=2 (x=h in vertex form y=a (x-h) ²+k)

Kinsley George · Answer 2

The axis of symmetry is the x value of the veretx

y=a (x-h) ^2+k

(h, k) is vertex

h=x value

f (x) = (x-2) ^2+3

x value is 2

x=2 is vertex

The function f (x) = 7 - 4x + x2 written in vertex form is f (x) = (x - 2) 2 + 3. What is the axis of symmetry for the function?x = - 3x = - 2x = 2x = 3
