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?

ohh sorry i wnet the wrong way
jim_thompson5910
  • jim_thompson5910
so you now see how I got \[\Large \lim_{x \to 60^{-}}f(x) = 56\] ??

?? you got me im still tring to figure this out this is my first problem like dis
jim_thompson5910
  • 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?

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?
anonymous
  • anonymous
umm 45
jim_thompson5910
  • jim_thompson5910
how are you getting 45 ?

i sorry i went to the right i ment 30

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

yeah
jim_thompson5910

ok, if you were to draw a vertical line through x = 40, where does this vertical line hit the graph?
anonymous
  • anonymous
44
jim_thompson5910
  • jim_thompson5910
and if you went slightly to the left, say to x = 38, where does the vertical line cross the function?
anonymous
  • anonymous
26 maybe
jim_thompson5910
  • jim_thompson5910
draw a line through x = 38 where does it cross the function curve
anonymous
  • anonymous
idk
jim_thompson5910
  • jim_thompson5910
do you see x = 38 on the x axis?
anonymous
  • anonymous
yes but this is so confusing
jim_thompson5910
  • 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

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

  • jim_thompson5910
draw a vertical line through x = 38 |dw:1440721857770:dw|
jim_thompson5910
  • jim_thompson5910
hopefully you see that we cross the function curve at (38,44) ? |dw:1440721890590:dw|
