If a function is of form f(x)=g(Z)h(z), then f'(x) - (h(z))d(g(z))dz+g(z)d(h(z))dz(h(z))2
True
False
For a function of the form f(x)=g(x)h(x), f'(x) will be
(h(x))d(g(x))dx−g(x)d(h(x))dx(h(x))2
If a function is of form f(z)=g(z)h(z), then f′(z)=(h(z))d(g(z))dz+g(z)d(h(z))dz(h(z))2
If a function f(x) is concave at x = a, then f”(a) < 0.
