Finding the Limit of g(x) and r(x) as x Approaches a Specific Value

[jessyca_lynne]

let g(x)= (x-3)sin(1/(x-3))+2. Determin ethe limit by any means possible as x-->3.


let r(x)=2+((sinx)/x)
find the limit of r(x) as x aproaches infinity

make a conjecture about the limit of r(x) as x approaches zero. give evidence to support your conjecture.

What have you done so far?

i don't know where to begin!

I suggest you use lim_{x\rightarrow a}(F(x)\cdot G(x))=lim_{x\rightarrow a} F(x) \cdot lim_{x\rightarrow a}G(x).

Well, do you know the definition of what it means to say

\lim_{x \rightarrow a} f(x) = L,

or

\lim_{x \rightarrow \infty} f(x) = L

?

I suggest you use lim_{x\rightarrow a}(F(x)\cdot G(x))=lim_{x\rightarrow a} F(x) \cdot lim_{x\rightarrow a}G(x).

This only works if both limits exist!
