# Graphing question

Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. Is it possible to sketch a function like 2x/(x^2 + 3) easily? without the table method.

It's not an improper fraction like x/x+3, so you can't split it with long division and then sketch it easily.

Things to check
Any asymtotes, any limits, oblique aysmptotes? When is it increasing/decreasing and any local maxima? Concave up or down on a range?
When function is 0 if ever zero.
Just evaluating these points and a few other things quickly gives you the graph easily.

3. Odd function.
4. y-intercept, also.

Thank you, I'll consider these points and try out questions and ask y'all if I face any problems.
