The function f is graphed over part of its domain on the coordinate axes below. The graph of y=f(x) has a horizontal asymptote at y=−1, two vertical asymptotes at x=1 and x=−2, x-intercepts at a and c where a<0<c, and a y-intercept at b<0.
Sketch the graph of y=∣f(∣x∣)∣ on the axes above, indicating clearly any asymptotes or axes intercepts.
Find the possible values of k such that the equation [f(∣x∣)]2=k has exactly 2 solutions.
