e^-x / e^-1 + 3 dx

Thank you..

**drwls**, Sunday, November 20, 2011 at 6:41amThe "dx" at the end makes me think you are supposed to integrate

[e^-x / e^-1] + 3 .

But that would make it a calculus, not a precalculus, question.

It is not clear what the question is. In any case,

e^-x / e^-1 = e^(1-x)

The integral of

e^(1-x) + 3 dx is

-e^(1-x) + 3x + C
