Math Problem Statement

The entire graph of the function h is shown in the figure below. Write the domain and range of h using interval notation.

Solution

To solve for the domain and range of the function hh as shown in the graph:

(a) Domain:

  • The domain represents all possible xx-values for which the function h(x)h(x) is defined.
  • Observing the graph, the function starts at x=3x = -3 and ends at x=4x = 4.
  • At x=3x = -3, the point is filled, indicating that x=3x = -3 is included.
  • At x=4x = 4, the point is open, meaning x=4x = 4 is not included.

Thus, the domain in interval notation is: [3,4)[-3, 4)

(b) Range:

  • The range represents all possible yy-values that the function h(x)h(x) can take.
  • The highest point on the graph occurs at y=4y = 4, and the lowest point occurs at y=3y = -3.
  • The highest value y=4y = 4 is included (filled point), while y=3y = -3 is also included (open point on the right does not affect range).

Thus, the range in interval notation is: [3,4][-3, 4]

Final Answer:

  • Domain: [3,4)[ -3, 4 )
  • Range: [3,4][-3, 4]
