$\lim_{x \rightarrow 2}f(x)+g(x)=f(2)+g(2)$ can u find f(2) and g(2) ?

3. monroe17

is that what I do for the first one?

4. hartnn

yup, find f(2) and g(2) then add.

5. monroe17

is f(2)=1?

6. hartnn

nopes, see the graph, when x=2, y=f(x)= 2 ok?

7. monroe17

8. hartnn

oh, wait, i think the dot is shaded to make the value of f(2) as 1. and not 2 so f(2)=1 as u correctly said before.

9. monroe17

oh kay.. so first one is 3?

10. hartnn

but g(2) is 0 isn't it? so, 1+0=1 is the value of limit, ok?

11. monroe17

huh?

12. hartnn

didn't u get g(2) = 0 ??

13. monroe17

ohh yeah.. because theres no point

14. hartnn

thats because when x=2,g(x) is on x-axis, so g(2)=0

15. monroe17

for the second one is f(x)= 1?

16. monroe17

and g(x)=1?

17. hartnn

yup,both correct,so whats the value of limit?

18. monroe17

2?

19. hartnn

yup,thats correct,try 3rd.

20. monroe17

and the next one is 0 overall right?

21. monroe17

f(x)=0 and because its multiplying the total limit is 0

22. hartnn

right,because f(0)=0

23. hartnn

i think u are getting this,so just write what answers u get,i'll verify.

24. monroe17

d is -1/0=0

25. hartnn

anything/0 = infinity so d is -infinity

26. monroe17

oh..

27. hartnn

e is simpler,what did u get for e ?

28. monroe17

e=8?

29. hartnn

yup :)

30. monroe17

f=2?

31. hartnn

absolutely, good work :)

32. monroe17

yay!!! thanks!

33. hartnn

welcome :)
