(Worth 19 points) I need help on doing inverse of an exponential function, not sure how to

Step-by-step explanation:

When doing the inverse of an exponential function, y = a^x is x = a^y.

So the equation would be x = 2^y

For example, if x = 1 then the equation would be 1 = 2^y where you solve for y.

1 = 2^y

y = 0

3x + 4y -25 =0 represents the amount of change sianna should recieve

to determine the unit cost your would divide the total cost by the number sold.
