Final answer:
Sofia made an error while finding the inverse of a function, and without specific steps, it is suggested that she carefully review her process and ensure correct application of inverse operations and algebraic principles.
Step-by-step explanation:
The question pertains to the process of finding the inverse of a function. Sofia is attempting to determine the inverse using her understanding that the natural logarithm and the exponential function are inverse operations. To find the inverse, the steps generally involve swapping the x and y variables in the equation of the function, and then solving for y. In Sofia's procedure, we do not have the specific step where she made a mistake, but generally, if an error is made, it could involve incorrectly applying inverse properties or algebraic manipulation. Sofia should review her steps carefully to ensure she follows this process correctly and corrects any algebraic errors.
