    Yes the derivative of e^x is e^x. And what is the derivative of ax-b? (a,b are constants)


    One suggestion. Don't write like that. Solving the problems without knowing the meaning of " ' " won't help you in future.

    You know that the derivative of e^x is e^x. Do you know the chain rule? Do you know how to find the derivative of f(x)+ g(x) if you know the derivatives of f and g separately? Do you know the derivative of a constant? (Remember that the derivative is the "rate of change"- how fast does a constant change?)
    Those are all things that are normally learned well before the derivative of the exponential.
