Answer:
Step-by-step explanation:
For this case we must determine the inverse of the following function:

Step 1:
We would write
or 
Step 2:
We clear x:


Step 3:
"x" and "y" are exchanged:

The inverse is:

Definitely irrational, and I'd say 1.4
7/438.... just solve it like thus.....EVERY FRACTION IS A DIVITION PROBLEM
