Question

What is the axis of symmetry for the function f(x)=7−4x+x2? edgunity

Answer 1

c on edge

Explanation:

took test

Answer 2

x=2

Explanation:

f(x)=7−4x+x^2

Rewriting as

= x^2 -4x+7

a =1 b -4 c=7

The axis of symmetry is

h = -b/2a

= -(-4)/ 2(1) = 4/2(1) = 4/2 =a

The axis of symmetry is x=2
