The following diagram shows the graph of y=f(x)
nm5qw z1yxtnz/k796q. T
kvl0y z (ke.:+lu)tdghe graph has a horizontal asymptote at y=-2 . The
kezd+(g)k0.l uyvl t: graph crosses the x -axis at x=-2 and x=2 , and the y axis at y=2 .
On the following set of axes, sketch the graph of $y=[f(x)]^{2}-1$ , clearly showing any asymptotes with their equations and the coordinates of any local maxima or minima.
