What is the derivative of 2x-1? Calculus Basic Differentiation Rules Power Rule 1 Answer Guilherme N. Jun 4, 2015 The power rule states that if y=a^n, y'=n*a^(n-1). Also, there's no derivative for constant, so it's zero, because there's no variation to de derivated. (dy)/(dx)=2 Answer link Related questions How do you find the derivative of a polynomial?
