• Given a quadratic function, which of the following choices explains the meaning of the zeros graphically. Which of the following equations could describe the function seen in the graph at the right?
• Equation 3 shows that the graph has a minimum when x = 5. This is because ( x − 5) 2 is always greater than or equal to zero and it takes a minimum value of 0 when x = 5.
• Quadratic equations are basically code for all variations of y = x squared. They form parabolas, which are bowl shaped graphs, either facing up or down. The worksheet contains the exact problems we cover in the video. Just print the sheet and work along with the class. Take the quiz right after the...
• By the end of this tutorial students will be able to label the vertex, line of symmetry and roots/zeros on a graph of a quadratic equation (parabola). Students will also be able to define parabola, quadratic equation, vertex, line of symmetry, and roots/zero. Lastly, students will be able to identify the shape of a quadratic equation (parabola) as a U-shaped graphs.

• f (x) = a x 2 + b x + c. has a vertex at the point (h , k) where h and k are given by. h = - b / (2 a) and k = f (h) = c - b 2 / (4 a) If a > 0, the vertex is a minimum point and the minimum value of the quadratic function f is equal to k. This minimum value occurs at x = h.
• In the previous lesson, you graphed quadratic functions using a table of values. In that lesson, I gave you the x values within the table of values. How would you know which x values to choose if you were graphing a quadratic function on your own? How would you be sure that you chose an x value that allowed you to graph the vertex?
