Question

help me plz

Answer 1

with?

Answer 2

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?

Answer 3

20

Answer 4

see attached

Answer 5

ohh sorry i wnet the wrong way

Answer 6

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

Answer 7

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

Answer 8

ok let's try another limit, like

\[\Large \lim_{x \to 40^{-}}f(x)\]

what is the value of this left hand limit?

Answer 9

50

Answer 10

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?

Answer 11

umm 45

Answer 12

how are you getting 45 ?

Answer 13

i sorry i went to the right i ment 30

Answer 14

hopefully we're still on the same page

Answer 15

yeah

Answer 16

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

Answer 17

44

Answer 18

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

Answer 19

26 maybe

Answer 20

draw a line through x = 38

where does it cross the function curve

Answer 21

idk

Answer 22

do you see x = 38 on the x axis?

Answer 23

yes but this is so confusing

Answer 24

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
