y=10^-x-4

Explanation:

To find the inverse, switch y and x. The inverse will look like:

x=-log(y+4)

However, we need to solve for y. Move the negative to the other side:

-x=log(y+4)

Assuming that the log is base 10, raise both sides to the power of 10. If the log is a different base, you will raise both sides to the power of that base:

10^-x=y+4

Subtract 4 on both sides:

y=10^-x-4
