Questions: Find the domain and range for the function shown in the graph given below. What is the domain? (Type your answer in interval notation.)

Solution Steps

Examine the graph to determine the range of x-values for which the function is defined. The graph starts at \( x = -20 \) and ends at \( x = 20 \).

Check if the endpoints at \( x = -20 \) and \( x = 20 \) are included in the graph. Both endpoints are marked with solid dots, indicating that they are included.

Since the function is defined for all x-values from \( -20 \) to \( 20 \) inclusive, the domain in interval notation is \([-20, 20]\).
