|---|---|---|---|---|---|
| parabola | the graph of a quadratic function
🗑
|
||||
| axis of symmetry | a line through the graph of a parabola that divides the graph into two congruent halves
🗑
|
||||
| vertex | the point at which the axis of symmetry intersects intersects the parabola
🗑
|
||||
| quadratic function | a function that contains a quadratic term, a linear term, and a constant term
🗑
|
||||
| maximum value | the greatest possible value a function can reach
🗑
|
||||
| minimum value | the lowest possible value a function can reach
🗑
|
||||
| quadratic equations | quadratic functions that are set equal to zero
🗑
|
||||
| roots | solutions of a quadratic equation
🗑
|
||||
| FOIL method | method that uses the Distributive Property to help multiply binomials
🗑
|
||||
| pure imaginary numbers | square roots of negative real numbers
🗑
|
||||
| complex number | any number that can be written in the form a+bi, where a and b are real imaginary numbers and i is the imaginary unit
🗑
|
||||
| completing the square | a method that can be used to solve all quadratic equations by using the Square Root Property and manipulating the equation until one side is a perfect square
🗑
|
||||
| discriminant | the expression b^2-4ac, which is used to determine the number and type of roots of a quadratic equation
🗑
|
||||
| standard form | ax^2+bx+c=0, where a does not equal zero and a, b, and c are integers
🗑
|
||||
| zeros | these are used to find the roots of a quadratic equation and are the x-intercepts of the graph of a quadratic equation
🗑
|
||||
| factored form | 0=a(x-p)(x-q), where p and q represent the x-intercepts of a graph of the equation
🗑
|
||||
| Zero Product Property | for any real numbers a and b, if ab=0, then either a=0, b=0, or both a and b equal zero
🗑
|
||||
| imaginary unit i | i^2=-1; the number i is the principal square root of -1
🗑
|
||||
| Square Root Property | a method that is similar to a difference of squares and is used to solve quadratic equations
🗑
|
||||
| factoring | finding the terms that are multiplied together to get an expression
🗑
