Math Problem Statement

match the function with its derivative

Match the function with its derivative

Solution

Let's analyze the graphs of the functions and their derivatives and match them accordingly.

Functions A-F:

  1. Function A: A straight line with a positive slope. This is a linear function, and its derivative will be constant (a horizontal line).
  2. Function B: A curve with a negative slope that steepens, levels out, and then steepens again. This could represent a cubic or higher-order polynomial. Its derivative will change its slope.
  3. Function C: A piecewise linear function with a V-shape, suggesting an absolute value function. The derivative will be a stepwise function with a slope of +1 and -1.
  4. Function D: A curve that decreases, levels out, and then increases. This resembles a cubic function.
  5. Function E: A parabola facing upwards. This represents a quadratic function, and its derivative will be linear.
  6. Function F: A curve decreasing steadily, representing a decreasing linear function.

Derivative Functions 1-5:

  1. Derivative 1: A parabola facing downwards, suggesting the derivative of a cubic function.
  2. Derivative 2: A straight line with a positive slope, matching the derivative of a quadratic function.
  3. Derivative 3: A horizontal line at 0, which is the derivative of a constant or a flat function.
  4. Derivative 4: A line with a negative slope, which matches the derivative of a function with a decreasing slope.
  5. Derivative 5: A step function, matching the derivative of an absolute value function (which has a V-shape).

Matching:

  • Function A (linear): Matches with Derivative 3 (horizontal line, constant derivative).
  • Function B (complex curve): Matches with Derivative 1 (a parabola facing downwards, derivative of a cubic function).
  • Function C (V-shaped): Matches with Derivative 5 (step function, derivative of absolute value).
  • Function D (cubic-like): Matches with Derivative 4 (a line with a negative slope).
  • Function E (parabola): Matches with Derivative 2 (a straight line with positive slope, derivative of quadratic).
  • Function F (linear, decreasing): Matches with Derivative 4 (a straight line with negative slope).

Here are five related questions to extend this discussion:

  1. What is the general process for differentiating polynomial functions?
  2. How do piecewise functions affect the shape of their derivatives?
  3. Can the derivative of a function change from being continuous to discontinuous?
  4. How do second derivatives relate to the concavity of the original function?
  5. What are the applications of matching functions with their derivatives in physics?

Tip: Remember that the derivative represents the slope of the tangent line at any point on the function.
