So unprofessional!
First of all, this is a problem from regular 8th grade Pre-Algebra. These kids have never seen a graph like this, yet they are expected to interpret it without any background information. Can you? Way too advanced in my opinion.
BUT, best of all, the students are supposed to find that the square root of 4 = 2. But there is no 2 on the x-axis! So even if they do understand what to do (doubtful), and line up their rulers perfectly, they cannot read the answer on the x-axis because it's not there!
Why are they so incompetent? They are frustrating the very kids they want to help - the ones who try hard and want to learn.
