A. Write True on the blanks provided if the statement is always true, and False if it is incorrect. For items 1-5, consider the function $ P(x)=a x^{3}+b x^{2}+c x+d $. 1.The graph of the polynomial function $ \mathrm{P}(\mathrm{x}) $ intersects the $ y $-axis at least once. 2. The graph of the polynomial function $ P(x) $ crosses the $ x $-axis in at most three points. 3. The end behavior of the graph of the polynomial function $ P(x) $ has both the left end and the right end in opposite directions. 4. The graph of the polynomial function $ P(x) $ passes through the origin. 5. The graph of the polynomial function $ \mathrm{P}(\mathrm{x}) $ has at most three turning points.

2) Write a program to simulate the processing of batch jobs by a computer system. The scheduling of jobs should be handled via a queue (or priority queue for more of a challenge). Examples of commands that your program should be able to process are • add -- to add an entry to the queue • delete -- to take an item out of the queue • status -- to report on items currently in queue
