Increasing and Decreasing Function

In calculus, the derivative of a function can be used to check whether the function is decreasing or increasing at any intervals in a given domain. For a given function, y = F(x), if the value of y and x are both increasing at the same time, then the function will be known as an increasing function and if the value of y is decreasing while the value of x is increasing, then the function will be known as a decreasing function.
