Question

Which of the following expressions represents a definite integral?

Options

• ∫ f(x) dx

• \[\int_{x=a}^{x=b}f(x)dx\]

• \[\frac {d}{dx}\]F(x)

• F(b) - F(a)

Answer 1

\[\int_{x=a}^{x=b}f(x)dx\]

Explanation:

This notation correctly shows an integral with specific lower (a) and upper (b) limits, which defines it as a definite integral.
