A number: n
five times a number: 5n
four less than five times a number: 5n - 4
four less than five times a number equals 11: 5n - 4 = 11
5n - 4 = 11
5n = 15
n = 3
The number is 3.

The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.
