Answer: At the top and bottom of the ∫ symbol.
- A As exponents attached directly to the ∫ symbol
- B At the top and bottom of the ∫ symbol
- C Inside the integrand alongside the function f(x)
- D Immediately after the dx differential term
Correct answer: B. At the top and bottom of the ∫ symbol
Explanation: In definite integral, limits appear at top (upper) and bottom (lower) of the integral symbol ∫.
The exact area under the curve from a to b (shaded) is approximated by a few rectangles, the Riemann sum idea behind the definite integral.
