    Find the vertex, line of symmetry, and the minimum or maximum value. f(x)=8-x^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 \[y=x^2\] \[y=-x^2\] \[y=-x^2+8\]
