Math Problem Statement

Find the range of the function graphed below. Enter your answer as an inequality.

Solution

To determine the range of the given graph, we need to identify the minimum and maximum values that yy can take.

  1. The line graph shows two distinct points:

    • The first point is open at (2,2)(-2, 2), which means this point is not included in the range.
    • The second point is closed at (4,10)(4, -10), meaning this point is included in the range.
  2. Observing the direction of the line, it is sloping downward from left to right. The range is determined by the yy-values of the function, which decrease as xx increases.

Range:

  • The highest yy-value is 2 (corresponding to the open point at (2,2)(-2, 2), but since it is an open circle, 2 is not included in the range).
  • The lowest yy-value is 10-10 (corresponding to the closed point at (4,10)(4, -10)).

Thus, the range of the function, written as an inequality, is: y>10 and y<2or10y<2.y > -10 \text{ and } y < 2 \quad \text{or} \quad -10 \leq y < 2.

  4. What are the implications of inequalities in graphing functions?
  5. Can the domain and range of linear functions ever be restricted by the graph?

Tip: When analyzing a graph, always pay close attention to open and closed points, as they affect whether boundary values are included in the range.
