The x-axis scales by one. Polynomial Function Graph. 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 draw the graph for the quadratic polynomial function f(x) = x 2. You can find the correct answer just by thinking about the zeros, and how the graph behaves around them (does it touch the x-axis or cross it).

So choice D is looking awfully good, but let's just verify Using the Factor Theorem, the equation for the graphed polynomial is: The Factor Theorem states that a polynomial function with roots(also called zeros) is given by the following rule. You can leave the function in factored form. In terms of end behavior, it also will change when you divide by x, because the degree of the polynomial is going from even to odd or odd to even with every division, but the leading coefficient stays the same. Direct link to ofehofili14's post y ultimately approaches p, Posted 2 years ago.
