Our compilation of printable inverse function worksheets should be an obvious destination, if practicing undoing functions or switching input and output values is on your mind. … 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 ...
