A composition of functions is when the output from one function is used as the input into another function. For f(g(x)), start with the g function and determine the output when x is the input. Be careful with the domain restrictions- you need to use the correct part of g! Once you have found the output from g(x), use that as the input into f(x). Again, read the domain restrictions carefully!
