Suppose h(t) is a twice-differentiable function with the known values:

Suppose h(t) is a twice-differentiable function with the known values:
h 0 1 2 3 4
H(t) 1 -4 -2 -1 -4
H^1(t) -9 1 3 1 -8
Justifying your reasoning, answer the following:
a) Determine where h(t) = 0 on the interval (0, 4).
b) Determine where h'(t) = 0 on the interval (0, 4).
c) Determine where h”(t) = 0 on the interval (0, 4).
