Which of the following curves is symmetric about the y-axis, making it easier to calculate its area by doubling the first-quadrant integral?
- A. y = x²
- B. y = x³
- C. y = eˣ
- D. y = ln(x)
Answer: A) y = x²
Explanation: A curve is symmetric about the y-axis if f(−x) = f(x). y = x² is an even function, thus symmetric about the y-axis.
