Final answer:
The error in the student's solution is that the function definition is incorrect. The correct solution is to rewrite the function definition properly. Assuming that in3(x) represents the inverse function of 3x and in(9) represents the inverse function of 9, the correct solution would be: win(x) = in3(x) - in(9)
Step-by-step explanation:
The error in the student's solution is that the function definition is incorrect.
The function win(x) is defined as the difference between in3(x), in(9), and 2in(3).
To correct the solution, we need to rewrite the function definition properly. Assuming that in3(x) represents the inverse function of 3x and in(9) represents the inverse function of 9, the correct solution would be:
win(x) = in3(x) - in(9)
