<h3>How to draw the graph of a Polynomial?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

We want to draw the graph of the function f(x) = 2(x – 1)2(x + 1)(x + 2). Using relevant coordinates input into the function and the generated output, the graph of the given function is as attached below.
