# What Is The Constant Rate Of Change

The constant rate of change is the average rate of change over a given interval. It is usually denoted by the symbol k and is constant if the rate of change is always the same. For example if a function f(x) represents the position of a car at time x then the constant rate of change of f with respect to x is the car’s speed. If the speed is always the same then the car has a constant rate of change.

The constant rate of change is found by taking the derivative of a function at a point and evaluating it. If the derivative is always positive the function is increasing at a constant rate. If the derivative is always negative the function is decreasing at a constant rate. If the derivative is 0 the function has no constant rate of change.

The constant rate of change can also be found by looking at the graph of a function. If the graph is a straight line then the function has a constant rate of change. The steepness of the line indicates the magnitude of the constant rate of change.

Constant rates of change are important in many areas of mathematics and science. In physics for example the rate of change of velocity is the acceleration. In calculus the constant rate of change is used to find the slope of a curve at a given point. It is also used in economics to find the marginal cost of a good or service.
