Thank you for trying to help me understand. We know that whenever a graph will intersect x axis, at that point the value of function f(x) will be zero. Make sure to observe both positive and negative [latex]a[/latex]-values, and large and small [latex]a[/latex]-values. For now, we will estimate the locations of turning points using technology to generate a graph. If x represents the number of shoes, and y is the cos So we know p of negative Using the Factor Theorem, the equation for the graphed polynomial is: y (x) = 0.125 (x + x - 14x - 24). Sometimes, a turning point is the highest or lowest point on the entire graph. [latex]f\left(x\right)=a{\left(x - \frac{5}{3}\right)}^{3}{\left(x+1\right)}^{2}\left(x - 7\right)[/latex]. This is where we're going 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.

The x-axis scales by one. Write an equation There is no imaginary root. 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. Now change the value of the leading coefficient ([latex]a[/latex]) to see how it affects the end behavior and y-intercept of the graph.
