Find the Derivative - d/dx 2x-1

Problem

d()/d(x)*(2*x−1)

Solution

1. Identify the expression as a linear function of the form ƒ(x)=a*x+b

2. Apply the sum rule for derivatives, which states that the derivative of a sum/difference is the sum/difference of the derivatives.

3. Differentiate the first term 2*x using the power rule, which results in 2

4. Differentiate the constant term −1 which results in 0

5. Combine the results to find the final derivative.

Final Answer

d()/d(x)*(2*x−1)=2
