Based on the given expressions,
Student 1: f(-1) = 2 + 7(-1)
Student 2: f(-1) = 2 - 7
Let's evaluate these expressions:
Student 1:
f(-1) = 2 + 7(-1)
= 2 - 7
= -5
Student 2:
f(-1) = 2 - 7
= -5
Comparing their results, we can see that both students obtained the same answer, which is -5.
Therefore, both students are correct in this case and there are no mistakes made.
