    Am I Right?

    interval e^x+1 dx

    interval e^u du

    e^u +c

    e^x+1 +c

    u=x+1
    du=1 dx

    If you mean:

    \int e^{(x+1)} dx

    you need to use brackets as what you have written is normaly
    interpreted as:

    \int e^x+1 dx

    Anyway:

    \int e^{(x+1)} dx=e \int e^x dx=e(e^x+c)=e^{x+1}+c'

    so yes you are right.
