Given that abcd is a rhombus, what is the value of x?

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.

Which term below correctly completes the following sentence? if a function has a vertical asymptote at a certain x value, then the function is what at that value
