Final answer:

To find the inverse of a function, follow these steps: Replace the function notation with y, swap the x and y variables, express y in terms of x, and replace y with the inverse function notation. If a mistake is made in step 2, it will result in an incorrect inverse function.

Step-by-step explanation:

To find the inverse of a function, we follow these steps:

  1. Replace the function notation with y.
  2. Swap the x and y variables.
  3. Express y in terms of x.
  4. Replace y with the inverse function notation.

If Sofia made a mistake in step 2, it means she didn't swap the x and y variables correctly. This would result in an incorrect inverse function. Therefore, Sofia made a mistake in step 2.
