Math Problem Statement

The user submitted an image containing a function analysis problem for g(x) and f(x), asking for information on domain, range, intercepts, extrema, intervals of increase and decrease, zeros, and continuity.

Solution

Let's analyze the contents of the image step-by-step. The exercise asks to analyze two functions, g(x)g(x) and f(x)f(x), with the following details provided:

Analyze g(x)g(x):

  1. Domain: (3,3)(-3, 3)
  2. Range: (2.2,1)(-2.2, 1)
  3. Absolute Maximum: Not applicable (N/A)
  4. Absolute Minimum: Not applicable (N/A)
  5. Intervals of increase and decrease:
    • The intervals of xx where g(x)g(x) is increasing and decreasing are left to be filled.

Analyze f(x)f(x):

Part 1: Function Evaluation

We are asked to evaluate f(x)f(x) at specific points, using the graph to the right.

  • f(0)f(0)
  • f(1)f(1)
  • f(2)f(2)
  • f(3)f(3)
  • f(4)f(4)

By analyzing the graph visually:

  • f(0)=0f(0) = 0
  • f(1)=1f(1) = 1
  • f(2)=0f(2) = 0
  • f(3)=3f(3) = -3
  • f(4)=1f(4) = -1

Part 2: Additional Information

We are asked to fill in the following about f(x)f(x):

  1. Domain: Based on the graph, the function seems to be defined for x(,)x \in (-\infty, \infty).
  2. Range: From the graph, it appears that the range of the function is approximately [3,2][-3, 2].
  3. X-intercepts (zeros): The graph crosses the x-axis at x=0x = 0, x=2x = 2, and x=3x = 3.
  4. Y-intercept: The y-intercept is at f(0)=0f(0) = 0.
  5. Absolute Maximum: The highest point on the graph is at f(1)=1f(1) = 1, so the absolute maximum is 11.
  6. Absolute Minimum: The lowest point on the graph is at f(3)=3f(3) = -3, so the absolute minimum is 3-3.
  7. Relative Maximum and Minimum:
    • Relative maximum occurs at x=1x = 1 where f(x)=1f(x) = 1.
    • Relative minimum occurs at x=3x = 3 where f(x)=3f(x) = -3.
  8. Intervals of Increase: The function increases on the interval (,1.5)(-\infty, -1.5) and (1,2.5)(1, 2.5).
  9. Intervals of Decrease: The function decreases on (1.5,1)(-1.5, 1) and (2.5,)(2.5, \infty).
  10. Zeros: As mentioned, the zeros are x=0x = 0, x=2x = 2, and x=3x = 3.
  11. For what value of xx is f(x)f(x) discontinuous?: The function appears continuous throughout its domain, so there is no discontinuity.

Would you like further details or explanations on any specific part? Here are five relative questions to explore:

  1. How do we determine intervals where the function is increasing or decreasing from a graph?
  2. What is the difference between absolute and relative extrema?
  3. How can we tell if a function is continuous or discontinuous?
  4. Why does f(x)f(x) have no absolute maximum or minimum outside the given intervals?
  5. How do x-intercepts relate to the zeros of a function?

Tip: When analyzing functions graphically, always check if the function is defined everywhere and if any breaks or holes indicate discontinuities.
