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. Below the math problem is described:
The figure above shows the graph of a function f, defined by f(x)=|2x|+4 for all numbers x. For which of the following functions g defined for all numbers x does the graph of g intersect the graph of f ?
A graph depicted the f(x) equation.
The answer ended up being g(x)=3x-2
…do you think you post a video as to how and why this is the answer?
