Watch Video on Graphing Quadratic Functions – Algebra Help
Access full lesson containing this video at: http://www.yourteacher.com/algebra1/graphingquadraticfunctions.php Students are introduced to the parent graph for quadratic functions: y = x^2. Students then learn how to graph quadratic functions, such as y = x^2 + 2, and how to identify the vertex, minimum, x- and y-intercepts, axis of symmetry, one pair of symmetric points, and the domain and range of the graph. Finally, students are asked to compare their graph with the parent graph for quadratic functions.

Thank you for …
Thank you for posting this i have a test tomorrow and this saved me. I hate teachers now days they suck at teaching like seriously. In a 7 minute video i learned more about parabolas then in a week of learning about parabolas in school.

“Remember that the …
“Remember that the graphs of all quadratic functions are parabolas.” That is ALL my first algebra teacher would have had to say for me to get it.
By the way, her vocal style is dreary and annoying.

When the parabola …
When the parabola opens down, it’s the highest point, and you take down the x value. :S

Minimum and max …
Minimum and max depend on if the x value is negative or positive, use the vertex formula to get you a number or x value then plug back into the equation to get the a y value. If in the equation your x value is positive then your set of coordinate has a minimum if it is negative then it will be maximum.
