Am i correct for this math question

Step-by-step explanation:

Hammers and Wrenches

I have included the graph to the first one. C is the best answer, but I don't think it is quite correct, although it is true. The actual fact is that there is no y intercept as near as I can get. That's an unusual occurrence for this kind of graph. There is no other answer that will satisfy or rectify that condition. I think you are likely to answer C, but be careful. It could turn out to be another answer.

f(x) and g(x)

I agree with your answer
