Question

What is the inverse of the function f(x)=\sqrt[3]{7x-21}-3f(x)= 3 7x−21 ​ −3f, (, x, ), equals, root, start index, 3, end index, square root of, 7, x, minus, 21, end square root, minus, 3 ?

Answer 1

given the equation is written in text so the signs and operators are weird, i don't understand the question but an inverse of any function can be found by switching f(x) or y with x.

For example if f(x) = 3x, then the inverse is x = 3y or y=x/3
