Question

Given the functions f(x) = 2x2 − 8x, g(x) = x2 − 6x + 1, and h(x) = –2x2, rank them from least to greatest based on their axis of symmetry.

Answer 1

for each function rewrite in vertex form same as set function = 0 and find the change in x value find the midpoint
the axis of symmetry is the x value of the vertex
put the these x-values in order from lowest to highest number on the number line
