Verified step by step guidance

Step 1: Recall the definition of an antiderivative. An antiderivative of a function f(x) is a function F(x) such that F'(x) = f(x). In this case, we are looking for a function F(x) whose derivative is 2x.

Step 2: Use the power rule for integration. The power rule states that the antiderivative of x^n is (x^(n+1))/(n+1) + C, where C is the constant of integration. Here, the term 2x can be rewritten as 2 * x^1.

Step 3: Apply the power rule to integrate 2x. Increase the exponent of x by 1 (from 1 to 2) and divide by the new exponent. This gives (2 * x^2)/2 + C, which simplifies to x^2 + C.

Step 4: Compare the result x^2 + C with the given options. The correct answer matches the first option: x^2 + C.

Step 5: Verify the solution by differentiating x^2 + C. Using the derivative rules, the derivative of x^2 is 2x, and the derivative of the constant C is 0. Therefore, the derivative of x^2 + C is 2x, confirming that x^2 + C is indeed an antiderivative of 2x.
