WebIn addition, if f and f-1 are inverse functions, the domain of f is the range of f-1 and vice versa. If the point (a, b) lies on the graph of f, then point (b, a) lies on the graph of f-1. How to determine if a function has an inverse. For a function to have an inverse, different inputs must correspond to different outputs. WebIn composition, the output of one function is the input of a second function. For functions f and g, the composition is written f ∘ g and is defined by (f ∘ g)(x) = f(g(x)). We read f(g(x)) as “f of g of x.”. To do a composition, the output of the first function, g(x), becomes the input of the second function, f, and so we must be sure ...
