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

2. mathsucksalot123

2?

3. brinethery

Nm, didn't see that that's the derivative. One sec.

4. mathsucksalot123

haha ok

5. TheOneGuy

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

6. brinethery

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.

7. TheOneGuy

Oh duh, ya you're on the right track brine

8. mathsucksalot123

Im still confused.

9. brinethery

Ugh, me too.

10. mathsucksalot123

haha tricky biz

11. brinethery

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

12. mathsucksalot123

hmm let me look at it

13. mathsucksalot123

That could be it. I just have to be certain cuz it gives me like one or two chances

14. brinethery

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

15. mathsucksalot123

No hahah it does but it so doesnt help at all

16. brinethery

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.

17. mathsucksalot123

thank you so much

18. brinethery

crap, I keep running into a brick wall. When do you have to turn this in?

19. brinethery

@pippa Are you good at these?

20. mathsucksalot123

Im tryingt o get it done tonight

21. mathsucksalot123

Do you think ur original idea is right

22. brinethery

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.

23. brinethery

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. :-(

24. brinethery

*delete

25. mathsucksalot123

ok thanks!

26. brinethery

I'm sorry I can't give you a straight answer, I feel bad.

27. mathsucksalot123

28. brinethery

After you repost this question, go back and delete the old post.
