Answer:
33. [-2, 8]
34.
[tex][8,\infty)[/tex]
35.
[tex](-\infty,-2][/tex]
Explanation:
Given:
Let's go ahead and graph the given functions as seen below;
See below the graph of f(x) = 2x - 5 if x < -2
The graph of x = -4x + 3 if -2 <= x < 8;
The graph of f(x) = 9 if x >= 8;
33) We can see from the second graph that the graph is decreasing, so we can see that the graph is increasing over the interval [-2, 8]
34) From the third graph, we can see that the graph is constant, so we can see that the graph is constant over the interval [8, infinity);
[tex][8,\infty)[/tex]
35) From the first graph, we can see that the graph is increasing. So we can say that the graph is increasing over the interval;
