POLQ 3 | Lesson 1 | Answers (Computation of Functions)

When functions are added or subtracted, the function stays at the same degree as the highest degree of the functions being added or subtracted. If two different linear functions are added or subtracted, the result will be a linear function.

If functions are multiplied, the degree of the function increases.  When two linear functions are multiplied, the result is a quadratic function. Three linear functions are multiplied together, the result is a cubic function.
