student one:
f(-1)= 2 + 7 (-1)
f(-1) = 9 (-1)
f(-1) = -9
student two:
f(-1) = 2 + 7 (-1)
f(-1) = 2 - 7

The input for both students is -1. The output, however, differs as student one obtained -9 while student two obtained -5. The difference in output can be attributed to the order of operations used in the function. Despite the difference in output, both students correctly used substitution to evaluate the function for the given input.
