Learn how to compose two functions where one or both of those functions is/are quadratic. To compose two functions means to express one of the functions as a function of the other function.

Function Notation is an easy way to display the input of a function. The f(x) is f of x and displays the input of the function. The f(x) is f of x and not f times x f is used most often but any letter can be used. When you evaluate a function you simply plug in the value for x into the output. For example, Evaluate f(x) = 2x + 5 If x =5 then ...
