Math Problem Statement

Shown above is the graph of a differentiable function f along with the line tangent to the graph of f at x = 2. What is the value of f'(2)?

Solution

The image shows a graph of a differentiable function ff along with a tangent line to the graph of ff at x=2x = 2. The question asks for the value of f(2)f'(2).

To find f(2)f'(2), which represents the slope of the tangent line to the graph of f(x)f(x) at x=2x = 2, we can analyze the slope of the tangent line shown in the graph.

Steps to Solve:

  1. Identify the coordinates of points on the tangent line:

    • From the graph, it appears that the tangent line passes through the points (2,2)(2, 2) and (4,4)(4, 4).
  2. Calculate the slope:

    • The slope mm of a line passing through two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is given by: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}
    • Plugging in the coordinates of the two points: m=4242=22=1m = \frac{4 - 2}{4 - 2} = \frac{2}{2} = 1
  3. Conclusion:

    • The slope of the tangent line at x=2x = 2 is 1, so f(2)=1f'(2) = 1.

Final Answer:

f(2)=1f'(2) = 1

Tip:

When analyzing graphs to determine slopes, try to use clear points on the line to minimize errors in calculating the slope.
