Question

Given the functions f(x) = 3x2, g(x) = x2 − 4x + 5, and h(x) = –2x2 + 4x + 1, rank them from least to greatest based on their axis of symmetry.

Answer 1

f(x) = 3 x^2
when x = 0 f(x) = 0
so what is the axis of symmetry of this function?

Answer 2

f(x)=0

Answer 3

no its x = 0 - in other words its the f(x) ( or y axis)
