# How does rate change?

It could increase or decrease.

One example of rate is speed. You can decide to go faster or slower. Another example is how much paint is applied per square meter. If you find that the previous color is faintly showing through the new coat, you can increase the application rate of the paint.

I hope this helps, Steve

Rate of change refers to how one quantity changes in relation to another quantity. It is often expressed as the ratio of the change in one quantity to the change in another quantity over a specific interval of time or space. In mathematics, rate of change is typically represented using calculus concepts, such as derivatives.

For example, if you have a function ( f(x) ), the rate of change of ( f(x) ) with respect to ( x ) at a specific point ( a ) is given by the derivative ( f'(a) ), which represents the instantaneous rate of change at that point.

In real-world scenarios, rate of change can represent various quantities such as speed, velocity, growth rate, or depreciation rate, depending on the context of the problem. It provides a measure of how one quantity is changing relative to another and is fundamental in analyzing and understanding dynamic systems and processes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
