Question

If a function f has an inverse and ​f(−​3)=​6, then f−1(6)=enter your response here

Answer 1

Hence, if we know the output of the original function for a given input, we can state that the input is actually the output of the inverse function when the input is the output of the original function. f ( α ) = β f − 1 ( β ) = α . Therefore, we have f − 1 ( 6 ) = − 3 .
