[问答题]
The following diagram
y7kc578niq f vinq- w46azhp;um8qto ;f;:xb shows the graph of y=f(x). The graph has a horizontal asymptote at y=-2. The graph crosses the x-axis at x=-2 and x=2
up8zb;afqmh t 6:;;ox, and the y -axis at y=2 .
$\text { On the following set of axes, sketch the graph of } y=[f(x)]^{2}-1 \text {, clearly showing any asymptotes with their equations and the coordinates of any local maxima or minima. }$
