Question #5ce0c

Answer 1

See explanation.

Explanation:

To find the inverse function you can do the following:

1. Write the formula of `y=f(x)`.

2. Transform it to calculate `x` as `f(y)`

The function you get in 2. is the inverse function.

Here we have:

`y=2^x - 3`

`2^x=y+3`

`x=log_2(y+3)`

Now we can change the letters `x` and `y` to get the function in the usual form with `x` as independent variable:

`y=log_2(x+3)`
