Math Problem Statement

A part of linear function g is graphed on the grid. Which inequalities best describe the range of the part shown?

Solution

To solve this problem, we need to determine the range of the linear function g(x)g(x), based on the graph shown.

Key steps:

  1. Examine the vertical axis (y-axis): This axis gives the values of g(x)g(x), which represent the function's output.
  2. Identify the minimum and maximum values of g(x)g(x): The lowest and highest points on the line segment shown in the graph represent the range.

From the image, it appears that:

  • The lowest value of g(x)g(x) is 3-3, as the graph touches the point at y=3y = -3.
  • The highest value of g(x)g(x) is 44, as the graph reaches up to y=4y = 4.

Thus, the range of the function g(x)g(x) is between 3-3 and 44, inclusive of 44, but not including 3-3 since the line does not touch the exact value.

Correct inequality:

The best inequality that describes this range is: 3<g(x)4-3 < g(x) \leq 4

Thus, the correct answer is the third option: Range: 3<g(x)4-3 < g(x) \leq 4.

Do you have any questions or would you like more details on the process?

Here are 5 related questions to expand on this:

  1. How do we define the domain of a function?
  2. What is the difference between the range and the domain?
  3. How would the graph change if the function had a range 4<g(x)5-4 < g(x) \leq 5?
  4. What does it mean for a function to have an "open" vs. "closed" interval for its range?
  5. How can we algebraically calculate the range of a linear function from its equation?

Tip: Always check whether the endpoints are included in the range or domain by observing if the graph touches those points exactly.
