Functions can be composed by passing the output of one into the other. We use the symbol ∘, and pay close attention to the order in which functions are composed:
To find an expression for f(g(x)), substitute g(x) for x in the expression for f(x).
Notice that for (f∘g)(x), we first pass x into g, and then pass that output into f.
Nice work completing Function Composition, here's a quick recap of what we covered:
