Math Problem Statement

Sketch a graph given the following key features: Domain (-4,4), Range (-4,6), Increasing (-4,1), Decreasing (1,4), X-intercept (-2,0), (3,0), Y-intercept (0,4), Negative interval (-4,-2) and (3,4), Positive interval (-2,3).

Solution

The image presents a problem where a graph is to be sketched based on key features provided. Below is an analysis of each feature:

  1. Domain: (-4, 4)

    • The graph exists between x=4x = -4 and x=4x = 4.
  2. Range: (-4, 6)

    • The yy-values of the graph range from 4-4 to 66.
  3. Increasing Interval: (-4, 1)

    • The graph is increasing from x=4x = -4 to x=1x = 1.
  4. Decreasing Interval: (1, 4)

    • The graph is decreasing from x=1x = 1 to x=4x = 4.
  5. X-intercepts: (-2, 0) and (3, 0)

    • The graph crosses the x-axis at x=2x = -2 and x=3x = 3.
  6. Y-intercept: (0, 4)

    • The graph crosses the y-axis at y=4y = 4.
  7. Negative Interval: (-4, -2) and (3, 4)

    • The graph is negative (below the x-axis) between x=4x = -4 to x=2x = -2 and x=3x = 3 to x=4x = 4.
  8. Positive Interval: (-2, 3)

    • The graph is positive (above the x-axis) between x=2x = -2 and x=3x = 3.

How to sketch the graph:

  • The graph starts at x=4x = -4, increasing until x=1x = 1, with points below the x-axis from x=4x = -4 to x=2x = -2.
  • The graph crosses the x-axis at x=2x = -2 and rises until it reaches the y-intercept at (0,4)(0, 4).
  • The graph continues increasing until x=1x = 1, where it reaches a maximum, and then begins decreasing.
  • It crosses the x-axis again at x=3x = 3 and dips below the axis between x=3x = 3 and x=4x = 4, while decreasing further toward x=4x = 4.

Would you like me to sketch the graph based on these details?

Here are five related questions:

  1. What type of function could represent this behavior?
  2. Can you determine the local maximum and minimum based on the intervals?
  3. How does the behavior of the graph change at x=1x = 1?
  4. What does the increasing and decreasing behavior suggest about the function's derivative?
  5. Can the x-intercepts help factor a possible quadratic or cubic equation?

Tip: Always consider the intervals of increase and decrease when analyzing the derivative behavior of a function.
