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

answers:

             f(x) = x² + 4x + 3, f(x) = –2x² – 8x + 1,

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
