1.8 Combinations of Functions Composite Functions. This example shows that knowledge of the range of functions (specifically the inner function) can also be helpful in finding the domain of a composite function. It also shows that the domain of [latex]f\circ g[/latex] can contain values that are not in the domain of [latex]f[/latex], though they must be in the domain of [latex]g[/latex]., The domain of a composition will be those values which can "move through" to the end of the composition. The "obstacle" is whether all of the values created by g(x), in this case, can be "picked up" by function f (x). Algebraic Interpretation of this example: 1. Function g(x) cannot pick up the value +2 since it creates a zero denominator. Consequently, the composition also cannot pick up the value of +2..

Here is another example of composition of functions. This time let f be the function given by f(x) = 2x and let g be the function given by g(x) = ex. As before, we write down f(x) ﬁrst, and then apply g to the whole of f(x). In this case, f(x) is just 2x. Applying the function g then raises e to the power f(x). So we obtain gf(x) = g(f(x)) = g(2x) = e2x. Composite Functions •In a composition of functions, the range of one function is part of the domain of the other function •Basically substituting one function into another function •Notation of composite functions is •f(g(x)) or (f g)(x) •Read as “f of g of x”
