1/3(3y-z) in distributive property

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

Is the point (0, 8) on the x-axis or y-axis? how do you know?

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.
