Question

Given the functions f(x) = 4x2 − 1, g(x) = x2 − 8x + 5, and h(x) = –3x2 − 12x + 1, rank them from least to greatest based on their axis of symmetry.
g(x), h(x), f(x)
f(x), h(x), g(x)
g(x), f(x), h(x)
h(x), f(x), g(x)

Answer 1

PLZZZZZZZZ HELPPPPP

Answer 2

\[f(x)=4x^2-1=4(x-0)^2-1 \rightarrow axis \space is \space x=0\\g(x)=x^2 − 8x + 5=(x-4)^2-16+5 \rightarrow axis \space is \space x=4\\h(x)= –3x^2 − 12x + 1=-3(x^2+4x)+1=-3((x+2)^2-4)+1 \rightarrow axis \space is \space x=-2\]

Answer 3

for the last one x=-2 is axis of symmetry
