[Calculus] Find the area under the given curves...f(x) = -3^e-3x –3x? Watch

1. Find the area under the given curves
f(x) = -3e-3x –3x between x = 0 and x = 2

'Area under the graph' implies you need to integrate.

Have you tried this? Post your working.
3. I've got it integrated as below:

e-3x - 3x2/2

Correct?

4. Yes. Now evaluate with the limits. (F(2)-F(0)) (EDIT)
5. Got an answer of 5.501.

Hows that? Thanks for you help
6. (Original post by yannispress)

Hows that?
Incorrect, I'm afraid. You should get something close to -7 for the integral, and hence the area of ~7
