So I have two graphs of the functions f and g. it says to find:
lim x--1 f(x)+g(x)
I can find the limit by looking but what should I do when it has f(x)+g(x)?

Question

So I have two graphs of the functions f and g. it says to find:
lim x->-1 f(x)+g(x)
I can find the limit by looking but what should I do when it has f(x)+g(x)?

sriram · Answer

add lim of f(x) & g(x)

anonymous · Answer

you sum f(x)+g(x)

anonymous · Answer

$$\lim_{x\rightarrow -1}[f(x)+g(x)]=\lim_{x\rightarrow -1}f(x) + \lim_{x\rightarrow -1}g(x)$$For more solutions to textbook problems, be sure to check out http://www.slader.com/s/eWFrZXlnbGVl . I submit a lot of content there as well.

anonymous · Answer

oh so whatever limit i get for f(x) i add that to the limit i get for g(x) right?

anonymous · Answer

Yep!

anonymous · Answer

Thank you everyone!

anonymous · Answer

i mean sum the function of f(x) and function of g(x) and then limit it

anonymous · Answer

^That works too, but can be harder in some situations.

anonymous · Answer

umm for the examples?

anonymous · Answer

what about when it has f(g(x))?
