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

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

- anonymous

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

- 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?

- anonymous

50

- 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?

- anonymous

umm 45

- jim_thompson5910

how are you getting 45 ?

- anonymous

i sorry i went to the right i ment 30

- jim_thompson5910

hopefully we're still on the same page
you're using this graph right?

yeah

- jim_thompson5910

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

- anonymous

44

- jim_thompson5910

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

- anonymous

26 maybe

- jim_thompson5910

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

- anonymous

idk

- jim_thompson5910

do you see x = 38 on the x axis?

- anonymous

yes but this is so confusing

- 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

- jim_thompson5910

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

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

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

- jim_thompson5910
