    This is so easy. What is y when x=1? What is y when x=2? when x=3? And so on.

    It looks like it would be simple - but where is the original function

    Okay, so we start at f(0) = 3. Well at f'(1), the slope is -4. So for finding f(1), we can start at f(0)=3. Then go down 4 on the y-axis and then go right 1 on the x-axis. Not sure how correct this is, let's see what others have to say.

    So I think f(1)=-1. Then go down 4 and over 1 to the right again. Then you'll have f(2)= -5

    I see. Does your book have any examples similar to this? I know how much of a pain these online assignments can be.

    Okay if you can give me a sec, I found a similar HW problem from Rogawski's book and I can get you a soln from cramster. Hopefully, it'll help a little.

    Now I'm thinking that you should start 0,3 and the function curves down until it gets to x=1. Seems to me like f(1)=2. But in all honesty, I would repost this question. Then go back and deletes this old post. Try to ask people in the chatbox as well.

    This is SUCH a visual thing and I can't believe they would ask something like this. I mean, you can understand the concept perfectly but still get this one wrong. :-(
