Not sure but I'm wondering if you have to individually get the limit of each function separately and then plug them in into the equation you are asked for. For example you would add the two limits for the first one

3. Nancy_Lam

how?

4. RyanL.

for a it says the limit of the function as you approach 1 from the left side.

5. RyanL.

for f(x) that would be 3 for g(x) that would be 5 so wouldn't it be 3+5 for a)

6. Nancy_Lam

$a) \lim_{x \rightarrow 1^{-}}$

7. Nancy_Lam

$1^{-}$write equation than plug x= 1(negative)?

8. RyanL.

no that means the limit of x approaches 1 from the left side, Negative means left Positive means right there's a jump discontinuity in x=1 so you will have two values. One different values that you approach from the left and one different from you approach from the right.

9. Nancy_Lam

ok,tk

10. RyanL.

This is for a) I run through the line starting from the left side and stop when x=1 whatever value i get is the limit for x=1 as it approaches from the left side

Can I get some feedback @Callisto

12. Nancy_Lam

ok

13. RyanL.

Understand?

14. Nancy_Lam

b,c and d I able do my own,TK

15. Nancy_Lam

yes I Understand

16. Nancy_Lam

i did feedback

17. experimentX

1) 5 + 3

18. experimentX

2) 4 + 2* 1

19. experimentX

do you get the pattern?

20. Nancy_Lam

no

21. experimentX

lim x->1- f(x) + g(x) = (lim x->1- f(x)) + (lim x->1- g(x))

22. experimentX

lim x->1+ f(x) + g(x) = (lim x->1+ f(x)) + (lim x->1+ g(x))

23. Nancy_Lam

tk

24. Nancy_Lam

I try give you a medal, but don' let me do it

25. experimentX

no probs ... can you do the other problem? lim x->1+ f(x) * g(x) = (lim x->1+ f(x)) * (lim x->1+ g(x))

26. Nancy_Lam

c) 3*5=15?

27. experimentX

yep ..

28. Nancy_Lam

TK,I have to go

29. experimentX
