Parabola
A parabola is a special curve on a graph that is shaped like an arch. Any point on a parabola is at an equal distance from a fixed point (the focus), and a fixed straight line (the directrix).
Quadratic
An equation where the highest exponent of the variable (usually "x") is a square (2). It is usually written ax^2+bx+c = 0
Example: 2x^2+5x-3 = 0
Example: 2x^2+5x-3 = 0
Vertex
The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
Axis of Symmetry
A line through a shape so that each side is a mirror image.
Maximum Value
Maximum Value is the greatest point on a parabola.
Minimum Value
Minimum Value is the least greatest point on a parabola.
Term
In Algebra a term is either:
- a single number
- a variable
- numbers and variables multiplied together.
First Differences
The differences between the y numbers.
Second Differences
The differences between the first differences.
Zeros (root)
Where a function equals the value zero (0).
Example: -2 and 2 are the zeros of the function x^2 - 4
Example: -2 and 2 are the zeros of the function x^2 - 4
