Let f be the function given by f(x) = 2xe^x. The graph of f is concave down when x > -1 x < -2 x > -2 x < -1 x < 0

$64-66$ Assume that all of the functions are twice differentiable and the second derivatives are never $0 .$ Suppose $f$ and $g$ are both concave upward on $(-\infty, \infty)$ . Under what condition on $f$ will the composite function $h(x)=f(g(x))$ be concave upward?
