    What will be the approaches to the following functions as Yp

    Hello guys I am wondering what the following functions will have as an approach (or what you call it)
    would be nice to have their derivatives aswell up to y''

    e^x+4x
    e^3x + sinx
    e^x-e^-x
    2sinx - cosx
    y''+y = sinx


    I have an exam after a few days, a bit worried

    e^x+4x
    Is this what you are after?

    \displaystyle \lim_{x\to \infty}e^x+4x= \infty


    \displaystyle (e^x+4x)'= e^x+4


    \displaystyle (e^x+4x)''= e^x

    I am not sure, can i use this as an assumption for a Y p?

    How can i tackle the rest of them?

    e^x+4x
    e^3x + sinx
    e^x-e^-x
    2sinx - cosx
    y''+y = sinx
