What is the area bounded by the curve, the x-axis and the line x = 4?
Answer
The correct answer is C: 32 square units. The curve from the previous problem is y = 4x. The area bounded by y = 4x, the x-axis, and x = 4 is ∫₀⁴ 4x dx = [2x²]₀⁴ = 2(16) = 32 square units.
A.8 square units
B.16 square units
C.32 square units✓ Correct
D.64 square units
Explanation
The curve from the previous problem is y = 4x. The area bounded by y = 4x, the x-axis, and x = 4 is ∫₀⁴ 4x dx = [2x²]₀⁴ = 2(16) = 32 square units.
