Question

Dorinae is confused. She is making a x to y table for y=|x+1|. She is trying to find y when x = -3, but she is not sure if she should find the absolute value first, or if she should first add 1. What should she do first?

Answer 1

Absolute values are treated the same way as brackets, therefore, you have to add one first (complete inside the brackets) 

i.e. 
y = |(-3) + 1|
y = |-2|
y = 2
