Derivative of exp^(2x-1)

1. Let $u = 2 x - 1$.

2. The derivative of $e^{u}$ is itself.

3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(2 x - 1\right)$:

   1. Differentiate $2 x - 1$ term by term:

      1. The derivative of a constant times a function is the constant times the derivative of the function.

         1. Apply the power rule: $x$ goes to $1$

         So, the result is: $2$

      2. The derivative of the constant $-1$ is zero.

      The result is: $2$

   The result of the chain rule is:

   $$2 e^{2 x - 1}$$

4. Now simplify:

   $$2 e^{2 x - 1}$$

The answer is:

$$2 e^{2 x - 1}$$
