Apply the EVT to the square function

The video tutorial explains the importance of having a continuous function on a closed interval to ensure the presence of maximum and minimum values. It demonstrates how to identify these values by checking the endpoints, using the extreme value theorem. The tutorial also includes a graph analysis to visualize the function's behavior over the interval.

What does the extreme value theorem state about continuous functions on closed intervals?

Describe the graph of a continuous function on the interval from zero to three based on the information provided.
