Figure 4.46 shows the second derivative of h(x) for -2 [tex]\leq[/tex] x [tex]\leq[/tex] 1
a) Explain why h'(x) is never negative on this interval.
b) Explain why h(x) has a global maximum at x=1
c) Sketch a possible graph of h(x) for this interval.
I realize this is probably a fairly simple question, however it's just making my head hurt.
