I'm having some difficulty on finding the inverse function for this problem.
I follow the first method of switching the 'x' and 'y' variables and then subtracting the from both sides, . Here's where my intuition breaks down. I know the objective is to solve for 'y'. Thus, multiply '0.2y' on both sides? .
Should I divide by ? That would give me
And then divide from both sides and I end up with
5 divided by 0.2 is 25, not 1
