What do you get when you graph a quadratic function? Not a line, that's the graph of a linear equation. The graph of a quadratic function is a curved line, either opening upward like a smile, or opening downward like a frown. The...

What things need to be done to graph a quadratic function? Well, first, find the axis of symmetry, then find the vertex of the parabola, then create a table and plug in some x-values to get the resulting y-values. Now write the values as...

Writing a quadratic equation in standard form gives values for a, b, and c that can be used to find several pieces of information about the graph of the equation. Knowing a, b, and c-values allows one to find the axis of symmetry, the...

This clip covers a lot of ground and is perfect for those needing a little extra help remembering how to graph a quadratic function. It begins with a multi-step problem which requires the learner to graph a quadratic function, set up a...

Video graphing a parabola by plotting the roots, vertex and axis of symmetry. Roots of the quadratic function are found by factoring. Vertex of the parabola is found by three different methods: taking the midpoint of the roots, finding...

Video graphing a quadratic function by evaluating it for seven different values and plotting the resulting points. [4:04]

Video defining the vertex and axis of symmetry for a parabola. Vertex is found for a specific function by completing the square to change the equation from standard form to vertex form and then reasoning through the equation. Axis of...
