how does one sketch graphs of functions such as x^2 - e^x? i know that you must first sketch the graphs x^2 and -e^x; but then what? how are they combined? i'm talking sketching here, it can't be that complicated.

Graph both functions like you have stated.

You then look to add the co-ordinates of each graph to find the result. Pick some points that are more obvious to add i.e at x =0 and build on that. - Jul 30th 2009, 10:58 PMfuror celtica
do you mean to say that the ordinates must be added?
