How do you evaluate functions The same way that you substitute values into equations Example 1 What is the value of $$ x $$ given the equation $$ y = 2x $$ when $$ x = 5 $$ Substitute 5 in for x The one new aspect of function notation is the emphasis on input and output Functions How to Decompose Functions You can decompose a function of x expressed as f x if a part of the equation can also be expressed as a function of x For example f x = 1/ x^2 2 You can express x^2 2 as a function of x and place this in f x You can call this new function g x
