# Thread: Limit Notation for a Log Function

1. ## Limit Notation for a Log Function

Use limit notation to discuss the end behavior of the function.

The log function is 11.2982 + 7.3723 ln x weight

I do not understand what the question is asking.

i guess they want $\displaystyle f(x) = 11.2982 + 7.3723 \ln x$

and you must find either $\displaystyle \lim_{x \to \infty} f(x)$ or $\displaystyle \lim_{x \to 0} f(x)$

does that ring a bell?

you need to help us out here, i for one am not sure what you want. haven't you done an example of this in class, or saw an example in your text or something?

3. I am lost. It is an internet course and the notes and power points the teacher put up don't have anything like this, and I have looked through all the examples in my text and can not find any examples even close to this.

well, do what i said. it makes sense. in general, when you want to find the end behavior (that is, what happens to the function at the ends, as you go far to the right and far to the left) you take the infinite limits. that is, the limit as $\displaystyle x \to \infty$ and the limit as $\displaystyle x \to - \infty$

here, however, the log is not defined for negative numbers, so we take the left end to be the limit as $\displaystyle x \to 0$. how does the function behave for those limits?
