1. use the following graph to find the following.\n(a) domain and range\n(b) intervals of increase and decrease\n(c) local extrema
Answer
Explanation:
Step1: Identify domain from x - values
The graph extends from (x=-2) to (x = 3). So the domain is ([-2,3]).
Step2: Identify range from y - values
The lowest (y) - value is approximately (y=-3) and the highest is (y = 7). So the range is ([-3,7]).
Step3: Determine intervals of increase
The function is increasing where the graph goes up as we move from left to right. This is on the intervals ([-2,0]) and ([2,3]).
Step4: Determine intervals of decrease
The function is decreasing where the graph goes down as we move from left to right. This is on the interval ([0,2]).
Step5: Find local maxima
Local maxima occur where the function changes from increasing to decreasing. At (x = 0), (y = 2) is a local maximum.
Step6: Find local minima
Local minima occur where the function changes from decreasing to increasing. At (x=2), (y=-3) is a local minimum.
Answer:
(a) Domain: ([-2,3]), Range: ([-3,7]) (b) Intervals of increase: ([-2,0]\cup[2,3]), Intervals of decrease: ([0,2]) (c) Local maximum: ((0,2)), Local minimum: ((2,-3))
