The cost to heat a house will depend on the average daily temperature, and in turn, the average daily temperature depends on the particular day of the year. The cost depends on the temperature, and the temperature depends on the day. By combining these two relationships into one function, we have performed function composition, which is the focus of this section.

We study formal notation and terms related to functions. We also define composition of functions and symmetry properties. Most of this material will be a review for you, but it serves as a handy reference to remind you of some of the algebraic techniques useful for working with functions.

Note that the domain of f composed with g is the set of all x such that x is in the domain of g and g(x)\) is in the domain of f. The domain of a composite function f∘g is the set of all inputs x in the domain of g for which g(x) is in the domain of f.

For example, in calculus, we learned how to form the product and quotient of two functions and then how to use the product rule to determine the derivative of a product of two functions and the quotient rule to determine the derivative of the quotient of two functions.

Function composition is only one way to combine existing functions. Another way is to carry out the usual algebraic operations on functions, such as addition, subtraction, multiplication and division. We do this by performing the operations with the function outputs, defining the result as the output of our new function.

To show that every element in this set is in the range, we need to show that for a given y in that set, there is a real number x such that f(x)=(x−4)2+5=y. Second, since the range of f is a subset of the domain of g, the output f(x) is an element in the domain of g, and therefore it is mapped to an output g(f(x)) in the range of g.
