Find the vertex, line of symmetry, and the minimum or maximum value.
f(x)=8x^2

x^2 is a turned over bowl so its max is its vertex y part

and the symmetry is the y axis since it never leaves its home

so the coordinates for the vertex are (2,8) ?

vertex is
\[\frac{b}{2a}\] for the first coordinate. in this case you might want to write
\[f(x)=x^2+8\] so b = 0 and the vertex is (0,8)

yikes mine are the worst! that is supposed to be
\[y=x^2\]
\[y=x^2\]
\[y=x^2+8\]
