1. ## Help me , please!

Evaluate the indefinite. Illustrate, and check that your answer is reasonalbe, by graphing both the function and its antiderivative.

$\displaystyle \int (2x+3)e^{x}dx$

I can't do it

Hi butbi9x,

You may want to try solving it by parts. (Say let $\displaystyle u = 2x+3$ and $\displaystyle dv = e^xdx$)

3. You can try using the Product Rule with the quantities (2x+3) and e^x.

This would be a good suggestion if the question was asking to find the derivative. However, the question asks for the anti-derivative.

5. "Illustrate, and check that your answer is reasonalbe, by graphing both the function and its antiderivative." --> I don't understand it , Check that my answer is reaonable by graphing ???

6. Oh I'm sorry I must have misread the question. You're absolutely right, thank you for pointing that out mr. fantastic. My apologies if I caused any confusion butbi9x.
