Why does the second derivative determine concavity?

The sign of the second derivative gives us information about its concavity. If the second derivative of a function f(x) is defined on an interval (a,b) and f ”(x) > 0 on this interval, then the derivative of the derivative is positive. Thus the derivative is increasing! In other words, the graph of f is concave up.
