Answer 1

`f^(-1)`(x) = x/2 - 3/2

Explanation:

Swap x and y and solve for y.

Original equation:

y = 2x + 3

Swapped equation:

x = 2y + 3

Now, solve for y:

x -3 = 2y

y = (x-3)/2

If it's wrong, it might just be the way you format your answer, since Pearson (what I assume you're using) is specific about that.

Maybe,
`f^(-1)`(x) = x/2 - 3/2 or
`f^(-1)`(x) = (x-3)/2
