## mathcalculus 2 years ago calculating the limit:

1. mathcalculus

2. FutureMathProfessor

The last one is obviously 1000

3. mathcalculus

yes but i tried sketching only it takes to long, and it says calculate

4. mathcalculus

@FutureMathProfessor do you know how to calculate? instead of sketching.

5. Idealist

The first one is undefined, the second one is 12, the third one is 1000 since it's undefined because the first 2 limits aren't equal to each other, which means undefined.

6. mathcalculus

are you guessing? @Idealist

7. mathcalculus

because it's wrong. the second one is ZERO.

8. mathcalculus

does anyone know how to calculate or not.

@idealist Might wanna check your arithmatic

11. Idealist

I'm not guessing. Since the first limit is -2-, which means you must plug in -2 into the function where it says x<-2, the second limit is -2+, which means you must plug in to x>-2, whatever you get, if these 2 limits don't have the same answer, then the last limit will be undefined and the answer will be 1000.

12. Idealist

And you're right, if you plug in -2 for the second limit, the answer is 0. I was mindless because I plugged in 2 instead of -2. But now you know it. I'm not guessing.
