with?

move to x = 60 on the graph curve then move slightly to the left of x = 60. Approach x = 60 and get closer and closer. What y value are you getting closer to?

4. anonymous

20

5. jim_thompson5910

see attached

6. anonymous

ohh sorry i wnet the wrong way

7. jim_thompson5910

so you now see how I got $\Large \lim_{x \to 60^{-}}f(x) = 56$ ??

8. anonymous

?? you got me im still tring to figure this out this is my first problem like dis

9. jim_thompson5910

ok let's try another limit, like $\Large \lim_{x \to 40^{-}}f(x)$ what is the value of this left hand limit?

10. anonymous

50

11. jim_thompson5910

find x = 40 on the x axis then slightly move to the left of x = 40 jump up to the function curve and get closer and closer and closer to x = 40 itself which y value are you getting closer to?

12. anonymous

umm 45

13. jim_thompson5910

how are you getting 45 ?

14. anonymous

i sorry i went to the right i ment 30

15. jim_thompson5910

hopefully we're still on the same page you're using this graph right? http://assets.openstudy.com/updates/attachments/55dfa1f2e4b0819646d755f0-tazmaniadevil-1440719400575-screenshot_2.png

16. anonymous

yeah

17. jim_thompson5910

ok, if you were to draw a vertical line through x = 40, where does this vertical line hit the graph?

18. anonymous

44

19. jim_thompson5910

and if you went slightly to the left, say to x = 38, where does the vertical line cross the function?

20. anonymous

26 maybe

21. jim_thompson5910

draw a line through x = 38 where does it cross the function curve

22. anonymous

idk

23. jim_thompson5910

do you see x = 38 on the x axis?

24. anonymous

yes but this is so confusing

25. jim_thompson5910

it sounds like you're not sure how to read a graph? or how to evaluate a function? I'm not exactly sure where you're stuck

27. jim_thompson5910

|dw:1440721609775:dw|

28. jim_thompson5910

ok here is x = 38. Somewhere between 20 and 40 on the x axis |dw:1440721837491:dw|

29. jim_thompson5910

draw a vertical line through x = 38 |dw:1440721857770:dw|

30. jim_thompson5910

hopefully you see that we cross the function curve at (38,44) ? |dw:1440721890590:dw|

31. anonymous

ohh

32. anonymous

yo can we kinda hurry i have church in n half an hour sorry to rush

33. jim_thompson5910

That's ok. We can work on this when you get back

34. anonymous

yeah i think ot i wont get bCK UNTILL MIDNIGHT

35. jim_thompson5910

that's fine
