The graph of the function is increasing at the interval x = 50 to x = 70
How to determine what happens at the interval x = 50 to x = 70?
From the question, we have the following parameters that can be used in our computation:
The graph
Also, we have the interval
x = 50 to x = 70
From the graph, we can see that
From x = 50 to x = 70
The value of the graph increase
This means that the graph is increasing at this interval
