Graphs of functions on the interval [0, 4] are depicted below. For each function, find its maximum and minimum values. The maximum value is:

The minimum value is:

To find the extremes, we must see the graph.

The maximum will be the value where the value of y is the greatest.

We can see that the graph peaks at y = 3.

Then the maximum is 3.

The minimum is the value of y that is the lowest.

We can see that in the left side, when x = 0, y takes the lowest value, y = -1

Then the minimum in the interval is -1.

The easier way to see maximum/minimum value is to look at the highest/lower value in the graph.
