Question
Answer each of the following.If two functions $f$ and $g$ are inverses, then $(f \circ g)(x)=$ ________________ , and _________________ $=x$.
Step 1
If $f$ and $g$ are inverses of each other, then the composition of $f$ and $g$ is equal to $x$. This is because applying $g$ first and then $f$ will just give you back the original input $x$. So, we have $(f \circ g)(x) = x$. Show more…
