## anonymous one year ago Given the functions f(x) = x2 + 6x − 1, g(x) = –x2 + 2, and h(x) = 2x2 − 4x + 3, rank them from least to greatest based on their axis of symmetry. f(x), g(x), h(x) h(x), g(x), f(x) g(x), h(x), f(x) h(x), f(x), g(x)

do you know how to find the axis of symmetry..?

2. anonymous

not when it is in standard form

3. karatechopper

You would need to convert to vertex form right? @campbell_st

4. anonymous

nvm -b --- 2a right?

5. campbell_st

ok... so if an parabola is in the form $y = ax^2 + bx + c$ the axis of symmtery is $x = \frac{-b}{2a}$ this may be familar as its part of the general quadratic formula so on the 1st question you have a = 1 and b = 6 so the axis of symmetry is $x = \frac{-6}{2 \times 1}$ just solve it hope that makes sense

then repeat the process for the 2nd and 3rd equations.

so fgh? A

8. campbell_st

makes sense to me

9. anonymous

not A
