6. Chain rule with function values.
Given F(4) = 1, F'(4) = 5, F(5) = 4, F'(5) = 6 and
G(1) = 3, G'(1) = 4, G(4) = 5, G'(4) = 6, find each of the
following. (Enter dne for any derivative that cannot be
computed from this information alone.)
A. H(4) if H(x) = F(G(x))
B. H'(4) if H(x) = F(G(x))
C. H(4) if H(x) = G(F(x))
D. H'(4) if H(x) = G(F(x))
E. H'(4) if H(x) = F(x)/G(x)
