Answer:

Step-by-step explanation:

f(x) = one of two values. There is a value given for what happens when x<>-1 and another when x is equal to minus 1. Which do you want?

Examine what f(x) means. It means that wherever you see an x value on the right, you put in the value shown for x on the left.

Try another example.

f(4) = 4^2 - 2*4     Whatever is shown on the left is put into the x on the right.

Same with your question

f(-1) means that the only possible answer is 5
