To graph a simple polynomial function, we usually make a table of values with some random values of x and the corresponding values of f(x). Then we plot the points from the table and join them by a curve. Let us
Use an online graphing calculator to find an odd degree function with one zero at (-3,0) whose multiplicity is 3 and another zero at (2,0) with multiplicity 2. The end behavior of the graph is: as x→−∞,f(x)→∞x→−∞,f(x)→∞ and as x→∞,f(x)→−∞x→∞,f(...
