Questions and Answers

What does the mean value theorem state?

  • The arc is always a straight line between its endpoints.
  • There is at least one point at which the tangent to the arc is parallel to the secant through its endpoints. (correct)
  • The tangent to the arc is always perpendicular to the secant through its endpoints.
  • There are multiple points at which the tangent to the arc is parallel to the secant through its endpoints.

    • What conditions must be satisfied for the mean value theorem to hold true?

  • $f(x)$ is continuous on the closed interval $[a, b]$ and differentiable on the open interval $(a, b)$. (correct)
  • $f(x)$ is continuous on the open interval $(a, b)$ and differentiable on the closed interval $[a, b]$.
  • $f(x)$ is differentiable on the closed interval $[a, b]$ and continuous on the open interval $(a, b)$.
  • $f(x)$ is continuous and differentiable on the closed interval $[a, b]$.

    • What does the mean value theorem guarantee the existence of?

  • A point $c$ in the closed interval $[a, b]$ where the tangent is parallel to the secant line through the endpoints.
  • A point $c$ in the closed interval $[a, b]$ where the tangent is perpendicular to the secant line through the endpoints.
  • A point $c$ in the open interval $(a, b)$ where the tangent is parallel to the secant line through the endpoints. (correct)
  • A point $c$ in the open interval $(a, b)$ where the tangent is perpendicular to the secant line through the endpoints.
