    Derivative of a function

    Find the derivative of a function using the power rule:

     f(x) = 2x -5\sqrt{x} +{e}^{ x+1}

    The only thing that is throwing me off is the {e}^{x+1 }

    We know that \frac{d}{dx}\left(e^x\right)=e^x

    Let u=x+1 \implies \frac{du}{dx}=1 and use the chain rule.

    OR you could simply see that e^{x+1}=e^1\cdot e^x
