**Ignore?**

b = 4

This graph does NOT represent ax² -1/4, where a would be a fraction less than 1.

vertex

The point where two sides meet. (Shared end points of the line segments of a polygon.)

turning point or extrema

the place where a function changes behavior from decreasing to increasing or from increasing to decreasing

Maximum

the highest possible y value for the graph of a quadratic function; also the y-coordinate of the vertex

Minimum

the lowest possible y value for the graph of a quadratic function; also the y -coordinate of the vertex

Domain

The ______________________ is all the possible INPUT, X, values.

Axis of Symmetry

a line that divides a parabola in two equal halves and goes through the vertex

f(x)=a(x-h)^2 +k

Vertex Form of a parabola

x=-b/2a

Find the line of symmetry

Standard Form of a Parabola

y = ax^2 + bx + c

How to graph Standard Form

Find line of symmetry (x= -b/2a)

Intercept (factored) form

f(x) = a(x-x1)(x-x2) where x1 and x2 are real zeros

How to graph factored form

Find x intercept by setting y to zero

How to graph vetrex form

Plot the vertex (h,x)
