Math Problem Statement

Suppose that the function h is defined as follows: - h(x) = -3 if -2.5 < x ≤ -1.5 - h(x) = -2 if -1.5 < x ≤ -0.5 - h(x) = -1 if -0.5 < x < 0.5 - h(x) = 0 if 0.5 ≤ x < 1.5 - h(x) = 1 if 1.5 ≤ x < 2.5 Graph the function h.

Solution

To graph the function h(x)h(x) based on its piecewise definition, let's analyze each segment:

Function Definition

The function h(x)h(x) is defined in five intervals:

  1. h(x)=3h(x) = -3 for 2.5<x1.5-2.5 < x \leq -1.5
  2. h(x)=2h(x) = -2 for 1.5<x0.5-1.5 < x \leq -0.5
  3. h(x)=1h(x) = -1 for 0.5<x<0.5-0.5 < x < 0.5
  4. h(x)=0h(x) = 0 for 0.5x<1.50.5 \leq x < 1.5
  5. h(x)=1h(x) = 1 for 1.5x<2.51.5 \leq x < 2.5

Steps to Graph

  1. For each interval, plot a horizontal line segment at the specified yy-value (e.g., -3, -2, -1, etc.).
  2. Indicate open and closed endpoints as specified in each interval.

Plotting Points and Line Segments

  • Segment 1: From x=2.5x = -2.5 to x=1.5x = -1.5 at y=3y = -3
    • Open circle at (2.5,3)(-2.5, -3) and closed circle at (1.5,3)(-1.5, -3).
  • Segment 2: From x=1.5x = -1.5 to x=0.5x = -0.5 at y=2y = -2
    • Open circle at (1.5,2)(-1.5, -2) and closed circle at (0.5,2)(-0.5, -2).
  • Segment 3: From x=0.5x = -0.5 to x=0.5x = 0.5 at y=1y = -1
    • Open circle at (0.5,1)(-0.5, -1) and open circle at (0.5,1)(0.5, -1).
  • Segment 4: From x=0.5x = 0.5 to x=1.5x = 1.5 at y=0y = 0
    • Closed circle at (0.5,0)(0.5, 0) and open circle at (1.5,0)(1.5, 0).
  • Segment 5: From x=1.5x = 1.5 to x=2.5x = 2.5 at y=1y = 1
    • Closed circle at (1.5,1)(1.5, 1) and open circle at (2.5,1)(2.5, 1).

Make sure to mark each endpoint correctly (open or closed) to match the domain restrictions.

Tip

When graphing piecewise functions, pay careful attention to the inclusion or exclusion of endpoints in each interval, as it influences the appearance and interpretation of the function’s graph.
