Quadratics

Quadratics

1. Roots of the Equation

   • the value (values) of x that makes the equation equal to zero.

2. Y-intercepts

   • where the graph crosses the y-axis

3. Vertex

   • the intersection of two sides of a plane figure.

4. Axis of symmetry

   • a straight line for which every point on a given curve has corresponding to it another point such that the line connecting the two points is bisected by the given line.

5. End Behavior

   • the behavior of the graph of f(x) as x approaches positive infinity or negative infinity.

6. Zeros of the function

   • an input value that produces an output of zero (0).

7. Minimum

   • the value of a function at a certain point in its domain, which is less than or equal to the values at all other points in the immediate vicinity of the point.

8. Parabola

   • the set of points in a plane that are equidistant from a fixed line and a fixed point in the same plane or in a parallel plane.

9. Difference of Squares

   • The formula for the difference of two squares can be used for factoring polynomials that contain the square of a first quantity minus the square of a second quantity.

10. Maximum

    • the value of a function at a certain point in its domain, which is greater than or equal to the values at all other points in the immediate vicinity of the point.

11. Factors of a Quadratic

    • finds the roots or x-intercepts of a quadratic equation.

12. X-intercepts

    • where the graph crosses the x-axis

13. Discriminant

    • a function of the coefficients of a polynomial equation whose value gives information about the roots of the polynomial.

14. Perfect Square Trinomial

    • A perfect square binomial is a trinomial that when factored gives you the square of a binomial.
