Math Problem Statement

(a) f ′(−3) (b) f ′(−2) (c) f ′(−1) (d) f ′(0) (e) f ′(1) (f) f ′(2) (g) f ′(3)

Estimate the value of each derivative from the given graph: (a) f ′(−3) (b) f ′(−2) (c) f ′(−1) (d) f ′(0) (e) f ′(1) (f) f ′(2) (g) f ′(3)

Solution

To estimate the value of each derivative f(x)f'(x) at the given points from the graph of f(x)f(x), we need to evaluate the slope of the tangent line at each specified point. The derivative at a given point represents the slope of the tangent line to the curve at that point.

Let’s analyze the graph:

  • At x=3x = -3: The slope is negative, as the curve is descending.
  • At x=2x = -2: The curve seems to be flat, meaning the slope (derivative) is zero, indicating a local minimum.
  • At x=1x = -1: The slope is positive, as the curve is increasing after the minimum.
  • At x=0x = 0: The slope continues to be positive.
  • At x=1x = 1: The slope is zero again, indicating a local maximum.
  • At x=2x = 2: The slope is negative, as the curve starts to descend.
  • At x=3x = 3: The slope is negative but less steep than at x=2x = 2.

Estimated values of the derivatives:

(a) f(3)1f'(-3) \approx -1 (negative slope) (b) f(2)=0f'(-2) = 0 (flat, local minimum) (c) f(1)1f'(-1) \approx 1 (positive slope) (d) f(0)1f'(0) \approx 1 (positive slope) (e) f(1)=0f'(1) = 0 (flat, local maximum) (f) f(2)1f'(2) \approx -1 (negative slope) (g) f(3)0.5f'(3) \approx -0.5 (negative but less steep)

Would you like a more detailed explanation of how each value was estimated, or do you have any other questions?

Here are 5 relative questions to deepen understanding:

  1. What does the derivative tell us about the behavior of a function at a point?
  2. Why is the derivative zero at local maxima and minima?
  3. How can the slope of the tangent line be approximated visually from a graph?
  4. What is the significance of positive versus negative slopes in a graph of f(x)f(x)?
  5. How could this graph be used to identify concavity or inflection points?

Tip: When estimating derivatives from a graph, look at how steep the curve is and whether it’s increasing or decreasing—this helps gauge the sign and magnitude of the slope.
