Concave interval calculator.
Convex mirror calculator. As you may have expected, a convex mirror is a mirror with a curved outward surface. It is a diverging mirror with the following convex mirror equation: \frac {1} {u} + \frac {1} {v} = \frac {1} {f} u1 + v1 = f 1. , so the lens mirror equation is basically the same as for concave mirrors.

On a given interval that is concave, then there is only one maximum/minimum. It is this way because of the structure of the conditions for a critical points.

If second derivative does this, then it meets the conditions for an inflection ...A closed interval notation is a way of representing a set of numbers that includes all the numbers in the interval between two given numbers. In this notation, the numbers at the endpoints of the interval are included in the set. The notation for a closed interval is typically of the form [a,b], where a and b are the endpoints of the interval.
Each graph bends upward and is therefore concave up.
