Question

Help with calc !

Answer 1

What would you like to know? Can you translate Question (a) into words?

Answer 2

(a) Find the limit of the function (given by the graph) as x approaches -2 from the right." How would you do that in practice?

Answer 3

would I get the equation and plus in -2? Not sure my teacher didn't explain this properly

Answer 4

the limit is ...not sure at all actually

Answer 5

Which one are you stuck on? Part a?

Answer 6

yes, im sure if I get the first one i'll be able to understand the rest

Answer 7

Maybe this will help a tiny bit :o

Answer 8

The tiny plus sign in the exponent is telling you "travel along the path from the larger side"

Answer 9

the right side*

Answer 10

You have two graphs on the left, one going through x=-2, the other stopping at the x-axis. Can't be both. Which do you mean? Zepdrix (who, as usual, is right on target) is assuming that you intended that the darker curve represent the function.

Answer 11

Yah that was strange. I didn't even notice the other line until now lol.

Answer 12

wait what

Answer 13

for the pic you sent me, a) y is approaching negative infinity ?

Answer 14

If x is decreasing, yes.
But for now please concentrate on (a).

Answer 15

No you don't keep going to the left.
See how my arrows are stopping at x=-2?

Answer 16

oh yes

Answer 17

approaching 0 ?

Answer 18

^ As the limit approaches -2 from the right, yes we approach 0

Answer 19

so for b, would it be limit approaches positive infinity?

Answer 20

for c it goes to zero again and im not sure for d

Answer 21

is that right ?

Answer 22

Now b)

As we approach 2 from the left side of the graph...what do we approach?



Looking at your graph, as we approach 2 from the left side, we approach what 'y' value?

Answer 23

oh um, we approach zero ?

Answer 24

Sorry I didn't draw in the 'y' values
