Math Problem Statement

The graph of a function is given. Use the graph to find each of the following: a. The domain and range of the function; b. The intercepts, if any; c. The intervals on which the function is increasing, decreasing, or is constant; d. Whether the function is even, odd, or neither.

Solution

Let's break down the question and analyze the function in the graph:

a. Domain and Range:

  • Domain: The domain refers to all possible xx-values the function can take. Based on the graph, the function spans from x=3x = -3 to x=8x = 8. Thus, the domain is: Domain:[3,8]\text{Domain}: [-3, 8]
  • Range: The range refers to all possible yy-values the function can take. The lowest point on the graph is y=3y = -3 and the highest point is y=1y = 1, so the range is: Range:[3,1]\text{Range}: [-3, 1]

b. Intercepts:

  • xx-intercept: The xx-intercept is where the graph crosses the xx-axis (where y=0y = 0). From the graph, the function crosses the xx-axis at x=1x = 1, so the xx-intercept is: \text{x-intercept}: (1, 0)
  • yy-intercept: The yy-intercept is where the graph crosses the yy-axis (where x=0x = 0). By estimating from the graph, the function crosses the yy-axis at approximately (0,1)(0, -1), so: \text{y-intercept}: (0, -1)

c. Intervals of Increasing, Decreasing, or Constant:

  • Increasing: The function is increasing (sloping upwards) from x=3x = -3 to x=4x = 4. Increasing on:(3,4)\text{Increasing on}: (-3, 4)
  • Decreasing: The function is decreasing (sloping downwards) from x=4x = 4 to x=8x = 8. Decreasing on:(4,8)\text{Decreasing on}: (4, 8)

d. Even, Odd, or Neither:

  • A function is even if it's symmetric with respect to the yy-axis, and odd if it's symmetric with respect to the origin. The graph does not appear to show symmetry about either axis, so the function is: Neither even nor odd.\text{Neither even nor odd}.

Would you like further clarifications on any part? Here are some related questions you could explore:

  1. What is the mathematical definition of domain and range?
  2. How can you determine whether a function is even or odd algebraically?
  3. How does symmetry play a role in determining whether a function is even or odd?
  4. What methods can be used to identify intervals of increasing and decreasing behavior without a graph?
  5. How would this function look if it were either even or odd?

Tip: When analyzing graphs, always look for intercepts, symmetry, and critical points to gather important information about the function!
