Answer
Explanation:
Step1: Check if it's a function
Use the vertical - line test. Since any vertical line intersects the graph at most once, it is a function.
Step2: Determine the domain
The graph exists for (x) values from approximately (x=- 8) to (x = 9). So the domain is ([-8,9]).
Step3: Determine the range
The (y) values range from approximately (y=-7) to (y = 8). So the range is ([-7,8]).
Step4: Find the (x) - intercepts
The graph crosses the (x) - axis at approximately (x=-6), (x = 2) and (x=5). These are the zeroes or (x) - intercepts.
Step5: Find the (y) - intercept
The graph crosses the (y) - axis at approximately (y = 1). This is the (y) - intercept.
Step6: Analyze the slope
There are parts with positive slope (e.g., from (x = 5) to (x=8)) and parts with negative slope (e.g., from (x=-8) to (x=-6)).
Step7: Check linearity
The graph is made up of line - segments, but overall it is nonlinear because it is not a single straight line.
Step8: Find minimum and maximum
The minimum value of (y) is approximately (-7) and the maximum value of (y) is approximately (8).
Step9: Determine increasing and decreasing intervals
Increasing intervals: approximately ((-8,-6)), ((2,5)) and ((5,8)). Decreasing intervals: approximately ((-6,2)) and ((8,9)).
Answer:
This is a function. The domain is ([-8,9]), the range is ([-7,8]). The (x) - intercepts are approximately (x=-6), (x = 2) and (x = 5), the (y) - intercept is approximately (y = 1). It has parts with positive and negative slopes. It is nonlinear. The minimum value is approximately (-7) and the maximum value is approximately (8). Increasing intervals are approximately ((-8,-6)), ((2,5)) and ((5,8)); decreasing intervals are approximately ((-6,2)) and ((8,9)).
