By the end of this tutorial students will be able to graph basic vertex form parabolas (with no reflections or dilations). Students will start with the vertex and follow a pattern for plotting five points (students can also create a table to help them find the points).
1) Write title at the top of the page
2) Draw Cornell line
3) Write all questions & answers
4) Write all examples
DISCRIMINANT: The part of the quadratic formula under the square root (b2 - 4ac). Tells the number of roots.
FACTORED FORM: Any quadratic equation in the form y = (x - a)(x - b)
FACTORING: To break up terms into smaller like terms (for this unit, to go from standard to factored form)
LINE OF SYMMETRY: The vertical line through the vertex, splits parabola into two mirror-image pieces
QUADRATIC EQUATION: A polynomial with a highest term of x2
QUADRATIC FORMULA: Formula solves for the roots of any standard form quadratic equation
PARABOLA: A graph of a quadratic equation
PERFECT SQUARE: A number that is square of another number (Ex: 9 is a perfect square, 9 = 3*3)
POLYNOMIAL: Any finite set of terms with positive exponents being added, subtracted, or multiplied
ROOTS/ZEROS: The point or points where a parabola intersects the x-axis.
STANDARD FORM: Any quadratic equation in the form: y = ax2 + bx + c
VERTEX: The point on the graph where the parabola changes direction from positive to negative or negative to positive
VERTEX FORM: An exponential equation in the form y = (x - h)2 + k
