Determine if the functions are inverses

WebMar 23, 2024 · To solve x^2 = 16, you want to apply the inverse of f (x)=x^2 to both sides, but since f (x)=x^2 isn't invertible, you have to split it into two cases. If x is positive, g (x) = sqrt (x) is the inverse of f, but if x is … 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 ...
