 You can find an axis of symmmetry of quadratic function by using this formula:

x=-\dfrac{b}{2a} \\ \\ \hbox{Where function is} \ \ f(x)=ax^2+bx+c \ \ \hbox{assuming} \ \ a\neq 0

An axis of f(x):

x=-\dfrac{6}{2 \cdot 1}=-\dfrac{6}{2}=-3

Of g(x):

x=-\dfrac{0}{2 \cdot (-1)}=\dfrac{0}{2}=0

Of h(x):

x=-\dfrac{-4}{2 \cdot 2}=\dfrac{4}{4}=1

At least to greatest you've got  -3, 0,  1   so f(x),  g(x),  h(x). Answer a
