The graph of a quadratic function has a unique shape called the
parabola.
Its turning point is called the
vertex
The line that divides the parabola into mirror images is called the
axis of symmetry
x value (axis of symmetry) formula
-b / 2a
y value formula
4ac - b² / 4a
y intercept
(0, c)
Domain
{ x I x ∈ R }
Range
{ y I y ≤/≥ value }
use brackets/parentheses facing INWARDS: when region B is
True
use brackets/parentheses facing OUTWARDS: when region B is
False
use ≤ in range if the opening is
Downward
use ≥ in range ig the opening is
upward
