    for part a), yes 2 if you put your pencil on the blue line and shifted the pencil up, you can see it crosses the red curve in to places.

    yes part a) there are 2 solutions for part b) if you slide the blue line down 5 steps, you think it crosses the red curve 4 times?

    Yes, 0 solutions. You should try to figure out how to answer this question. (Why did you not see the how to get the answer ?)

    When I get confused and then learn the answer (and I understand the answer), I go back and try to figure out why I was confused.
