WebAn inverse function is a function that undoes the action of the another function. Using function machine metaphor, forming an inverse function means running the function machine backwards. The backwards function machine will work only if the original function machine produces a unique output for each unique input. WebGiven a function f ( x), we can verify whether some other function g ( x) is the inverse of f ( x) by checking whether either g ( f ( x)) = x or f ( g ( x)) = x is true. We can test whichever equation is more convenient to work with because they are logically equivalent (that is, if one is true, then so is the other.) tabetha\u0027s instructions

"WebAn inverse function f-1(x) is the “reverse” of a function f (x). The x and y variables (and thus their domain and range) are flipped, and their composition gives us the identify f (f-1(x)) = x = f-1(f (x)). A function must be bijective (injective & surjective, or one to one & onto) to have an inverse. " - Give inverse of function
