Knowing the following set of functions helps you to describe the change in income, the growth of your company, the number of COVID-19 cases, …

Summary and Outlook

You’ve just seen 5 classes of functions which are relevant when talking about growth. Logarithmic functions are always increasing, but very slow. Faster are linear and quadratic functions.
