Question

Given the functions f(x) = x^2 + 6x - 1, g(x) = -x^2 + 2, and h(x) = 2x^2 - 4x + 3, rank them from least to greatest based on their axis of symmetry.
A.) f(x), g(x), h(x)
B.) h(x), g(x), f(x)
C.) g(x), h(x), f(x)
D.) h(x), f(x), g(x)

Answer 1

I think its A but I'm not sure

Answer 2

for each of them the axis of symmetry is \[-\frac{b}{2a}\] you have to compute that three times

Answer 3

oh yes, you are right \[-3,0,1\]

Answer 4

Thank you(:
