Question

Check my work?

Answer 1

@zepdrix First day of Calculus!!!!! Yay!!!

Answer 2

Cool, I think 1g may be infinity.

Answer 3

I wasn't sure, because for a limit to exist it has to be true from the right side and the left side... I don't know

Answer 4

ah well by that definition you shouldn't be able to do either infinite limit.

Answer 5

First day of Calc?? Ooooo exciting :D

Answer 6

I know! My teacher seems pretty cool too :D

Answer 7

I'm the only white kid in the class - everyone else is asian

Answer 8

LOL

Answer 9

Ya 1g, the arrow is pointing upward, infinity, ya?
Looks like the function is growing up .. becoming a man.

Answer 10

The rest of number 1 looks correct.
Seems like you've got a good handle on this.

This is the way I like to think of limits,
limits are all about the lines, not the dots.
Follow the line, wherever the line ends, that's your limit, ignoring the dot.

Answer 11

Hahaha xD
What about the left side though? If it were coming from the left side, would it still be approaching infinity?

Answer 12

For 1g

Answer 13

There is no left side of `positive infinity`.
positive infinity means as far right as possible.
Keep going and going and going to the right, what ends up happening?
The function just keeps going up up up.

Answer 14

No left/right for infinite limits.

Answer 15

Ah... okay. Limits of infinity and negative infinity don't have left/right. Got it.
Does the rest look right?

Answer 16

So same problem with 2h, fix that one up also.

Answer 17

2h should be negative infinity right?

Answer 18

Yes.
And 3 looks all correct.

Answer 19

Woops 4d,e,f

Answer 20

and 4g

Answer 21

5 looks great!

Answer 22

4d, e and f should all be 0
4g should be infinity
right?

Answer 23

Then try this problem next maybe :D
