Determining the Axis of Symmetry of Quadratic Functions Which functions have an axis of symmetry of x = –2? Check all that apply
. f(x) = x2 + 4x + 3 f(x) = x2 – 4x – 5 f(x) = x2 + 6x + 2 f(x) = –2x2 – 8x + 1 f(x) = –2x2 + 8x – 2

Answer:
Step-by-step explanation:
To find axis of symmetry we apply formula
a= 1, b= 4
Axis of symmetry at x=-2
a= 1, b= -4
Axis of symmetry at x=2
a= 1, b= 6
Axis of symmetry at x=-3
a= -2, b= -8
Axis of symmetry at x=-2
a= -2, b= 8
answers:
f(x) = x² + 4x + 3, f(x) = –2x² – 8x + 1,
