Quadratic Functions: Standard Form

Question 14 • FL-1200700-Mathematics for College Algebra MIS

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

Answer

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
