Math Problem Statement

Answer this

The entire graph of the function g is shown in the figure below. Write the domain and range of g as intervals or unions of intervals.

Solution

From the graph provided, let's determine the domain and range of the function gg.

Domain: The domain of a function refers to all the possible input values (x-values) for which the function is defined. Here, the function gg is defined for xx values starting just below 5-5 and ending at 33. These points can be described as closed points since the graph includes the endpoints at x=5x = -5 and x=3x = 3. Thus, the domain in interval notation is: Domain: [5,3]\text{Domain: } [-5, 3]

Range: The range of a function is the set of all output values (y-values) that the function can take. Observing the graph:

  • At x=5x = -5, y2y \approx 2
  • The highest yy-value appears at about y=4.5y = 4.5 when xx is around 4-4.
  • From x=4x = -4 to x=3x = 3, the function decreases, reaching a minimum of y=3y = -3 at x=3x = 3.

Therefore, the function reaches all yy-values from about 3-3 to 4.54.5. Thus, the range in interval notation is: Range: [3,4.5]\text{Range: } [-3, 4.5]

Here are the answers for the domain and range in the format requested:

  • Domain: [5,3][-5, 3]
  • Range: [3,4.5][-3, 4.5]

Would you like more details or help with another question?

Here are five related questions to expand upon the information:

  1. How would the domain and range change if the graph extended beyond x=3x = 3?
  2. What happens to the domain and range if the graph is reflected over the x-axis?
  3. Can you find a function that fits the graph provided?
  4. How would you describe the behavior of the function between x=5x = -5 and x=3x = -3?
  5. What mathematical concepts are applied when determining the domain and range from a graph?

Tip: When determining the range from a graph, look for the highest and lowest points the function reaches, along with any other constraints provided by the graph's context.
