Don't know how to find x given these segment lengths

For the quadratic function [tex]y=(x+4)^2-1[/tex] , do the following: a) rewrite the function in the standard form, b) rewrite the function in intercept form, c) find the vertex, d) find the y-intercept, e) find the x-intercepts.

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1
