the vertex is (10,-8)

sorry if im late

mathmale · Answer

the function is actually y=(x-10)^2-8.  Must use the operator " ^ " to denote exponentiation.

Compare this to the vertex form of the equation of a parabola:

                                     y=(x-h)^2+k

You can see that h=10, k=-8.  From this you know that the vertex is at (10,-8).

You need to know the standard equations of a parabola, to which you can compare any given equation of a parabola to determine the parameters (which, in this case, are h and k, the x- and y-coordinates of the vertex.
