Question 74.

As we see in the graph, the line goes up till it reaches the point (1, 3) i.e., for all the x less than 1, the function is increasing. Then we see that the graph is at the same level till it reaches the point (4, 3). which means the function neither increases nor decreases in the interval [1, 4].

then we can see that the graph is going down. Hence ...

Solution Summary

The readings from the graph of the function are accumulated to make the relevant observations about the function.
