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

Thank you..

• Pre-Calculus -

The "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

Thank you. You helped greatly.
