1. 3.14
Step-by-step explanation:
If we have
That just equals
For example, consider function
The inverse of that function is
So
If we compose the function, f(x) into f^-1(x).
We get
That proof of that.
1. Here x=f^-1(3.14)and f(3.14) cancel out so the answer is 3.14
2. We first find f(-7) which is -12,
We then find f(-12)= 5 so the answer here is 5.
