Here’s a question that one of our students sent in– ask and you shall receive! 🙂
“Hello team Magoosh. First I’d like to say I love this site, I’ve learned so much! I’m posting a question about a certain math problem I found on the official ETS website. I tried to solve it and got it wrong.
…do you think you post a video as to how and why this is the answer?

You may also want to check out absolute value basics. Let us know if you have any questions about this (or anything else GRE-related!).
Hi,
Would you please explain why the answers can’t be g(x) = x-2 or g(x)= x + 3? Thank you!
I still don’t understand why the answer can’t be D: y=2x+3? If you graph this on the graph, doesn’t it intersect y=2x+4? Because with y=2x+3, it starts at 3 and it goes up 2 and over 1 so just the first time it does that doesn’t it cross the origin of the absolute value graph? Does crossing the origin not mean intersect?
Hi Niraj,
Since y = 2x+3 and y = 2x+4 both have the same slopes they will parallel to each other, and thus will never intersect. y = 2x+4 will be one point “higher” than y = 2x+3.
Hope that helps!
Thanks!
Hey, I appreciate the explanation, makes perfect sense now!
Great! I’m happy it made things clear
