Question

If F (7) 22, Then F(f-1(22))

Answer 1

Answer: 7

Explanation:

Answer 2

`\boxed{\boxed{f(f^(-1)(22))=22}}`

Explanation:

`\text{If we have}\ f(x)\ \text{and}\ f^(-1)(x),\ \text{then}\\\\\text{if}\ f(a)=b,\ \text{then}\ f^(-1)(b)=a.\\\\\text{Therefore, if}\ f(7)=22,\ \text{then}\ f^(-1)(22)=7.\\\\f(\underbrace{f^(-1)(22)}_(=7))=f(7)=22`
