Answer:1. The function is increasing in the intervals (-5, -2) and (3, 5).
2. The function is decreasing in the intervals (-4, -1) and (2, 3).
3. The local extrema are (-2, -40) and (2, 40).
4. The estimated domain is -5 ≤ x ≤ 5, and the estimated range is -60 ≤ y ≤ 60.
Step-by-step explanation:1. To estimate the intervals where the function is increasing, we look for sections of the graph where the y-values are getting larger as the x-values increase. From the graph, it appears that the function is increasing in the interval from x = -5 to x = -2 and also in the interval from x = 3 to x = 5.
2. To estimate the intervals where the function is decreasing, we look for sections of the graph where the y-values are getting smaller as the x-values increase. From the graph, it appears that the function is decreasing in the interval from x = -4 to x = -1 and also in the interval from x = 2 to x = 3.
3. To estimate the local extrema, we look for points where the function reaches a maximum or minimum value. From the graph, it appears that there is a local minimum at the point (-2, -40) and a local maximum at the point (2, 40).
4. To estimate the domain of the graph, we look at the x-values that are included in the graph. From the graph, it appears that the domain includes all x-values from -5 to 5.
To estimate the range of the graph, we look at the y-values that are included in the graph. From the graph, it appears that the range includes all y-values from -60 to 60.
