Question #af0ab

Answer 1

`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`
