Evaluate the integral from 0 to 2 of (x^2 + 3) dx.
Answer and explanation
Correct answer: D. 26/3
- Step 1: An antiderivative is F(x) = 1/3x^3 + 3x.
- Step 2: F(2) - F(0) = 26/3 - 0 = 26/3.
Answer
26/3.
Why not the others: The coefficient of x^2 must be divided by 3 in the antiderivative and the constant term must contribute c(b - a).
