Question

I need help with this question. I have no clue how to solve and don’t know how to put in calculator.

Answer 1

A

Explanation:

We only need to calculate one of the functions shown. I will be using |x| - 1 because it is the simplist.

|x| makes a V shape and we know it only goes from -1 to 1. And that means it can be A or D. Next we apply the -1 so that it will go down. The only option that fits this is option A.
