#### To determine

If the provided statement is true or false.

#### Answer

True

#### Explanation

**Given:**

If f is one-to-one, with domain R, then f−1(f(6))=6.

Let f(x)=y.

This implies:

f−1f(x)=f−1(y)x=f−1(y)

So, f−1 makes *y* go back into *x*.

Thus, f−1(f(6))=6

**Conclusion:** Hence, the given statement is true.
