A Plot Of A Second Degree Function With Apparently A Single Root The curve of a second degree polynomial function is called a parabola. to sketch the graph, locate the vertex and draw two symmetrical branches. The key to sketching a function like this quickly is seeing that it's just the parent function of all cubic functions, $y=x^3$, shifted to the right by 2 units and inverted across the $x$ axis. Find the roots of f (x), and sketch the graph of y = f (x). solution. x2 −2 x −3 = (x 1) (x − 3). therefore, the roots are −1 and 3. (see lesson 37 of algebra.) they are the x intercepts of the graph. the y intercept is the constant term, −3. Some graphs have double, triple, quadruple, etc., roots. the graph below has a single, double, and triple root. the first root on the left side is a single root because it only touches the x axis once. the second root is a double root because it "kisses" the x axis.

The combined figure appears to be an ellipse. question: in step 2, where does the number 3 that multiplies the three term radical come from? is this 3 the square root of 9 that was factored out of inside the radical? wonder if someone knows the answer. where does this 3 comes from. thank you. Explore math with our beautiful, free online graphing calculator. graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. This demonstration is meant to show how the shape of the graph of this function depends upon the values of its coefficients a, b, and c. change these coefficients by clicking on the buttons near their values and notice how the this alters the form of the graph. A polynomial of degree 2 has two zeros or roots. in this representation you can see cassini ovals and a lemniscate.
