Question

If y = |x + 1|, then what is the value for x = -2?

A. -1

Answer 1

Sustitute -2 where the "x" is and get the resulting numerical value. If that value is negative, then drop the negative sign.

Answer 2

So, start with -2 + 1

What is that value?

Answer 3

The general way to look at it is:

|x| = -x if x is negative

|x| = x if x is positive.
