    Red face Help me , please!

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

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

    I can't do it

    Hi butbi9x,

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

    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.

    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.
