(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

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
