Evaluate the definite integral of 2x from x = 1 to x = 4.
Answer and explanation
Correct answer: A. 15
- Step 1: The integral of 2x is x^2. Step 2. x^2 evaluated from 1 to 4 is 16 - 1 = 15. Answer: 15. Why not the others: 16: That is the value of x squared at 4 only. 6: That subtracts the values of 2x instead of its integral. 17: That adds the values of x squared at the limits.
