Question

Find the vertex of the graph of the function. f(x) = (x - 10)2 - 8

Answer 1

Could I help you?

Answer 2

If you still need help, let me know!

Answer 3

the vertex is (10,-8)

Answer 4

sorry if im late

Answer 5

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).

Answer 6

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.
