Math Problem Statement

A Calculus student evaluated the limit as x approaches 2 for (f(x) - f(2)) / (x - 2). What knowledge about our function does the outcome provide?

Solution

The problem is asking what information the limit limx2f(x)f(2)x2\lim_{x \to 2} \frac{f(x) - f(2)}{x - 2} provides about the function.

This expression is the definition of the derivative of f(x)f(x) at x=2x = 2. Therefore, the limit gives the slope of the tangent line to the function at x=2x = 2.

Thus, the correct answer is:

  • The slope of the tangent line to the function at x=2x = 2

Would you like more details or have any further questions?

Here are five related questions to expand your understanding:

  1. What is the geometric interpretation of the derivative?
  2. How do you compute the derivative of a function at a specific point?
  3. What is the difference between the average rate of change and the instantaneous rate of change?
  4. How can the existence of vertical or horizontal tangent lines be determined?
  5. How do you find the equation of the tangent line at a given point?

Tip: The derivative gives the instantaneous rate of change of a function at any point. It can be seen as the slope of the tangent line to the curve at that point.
