Properties of monotonic functions. If f(x) is a strictly increasing function on an interval [a, b], then f −1 exists and it is also a strictly increasing function. WebWe learned before that, when x is a critical point of the function f(x), we do not learn anything new about the function at that point: it could increasing, decreasing, a local maximum, or a local minimum. We can often use the second derivative of the function, however, to ﬁnd out when x is a local maximum or a local minimum.

WebIf f ′ ( b) is positive, the function is increasing on that entire interval . This is because f ′ ( x) is positive at x = b, and can't change sign anywhere else in the interval (similarly if f ′ ( b) is negative). Remember: f ′ ( x) can only change sign at critical points! WebThe function would be positive, but the function would be decreasing until it hits its vertex or minimum point if the parabola is upward facing.
