The graphof a linear

functionis a straight

line, which is often

identifiedin termsof

its slopeand its y-in-

tercept.

The slopeof the line

is the coefficient ½,

and the y-interceptis

the constant1.

Linear y=x

2. The graph is a
   parabola,whichhas
   a vertexthat is either
   a globalmaximumor
   minimum of the
   graph.

The vertex is the

point(1,0).The graph

is symmetricacross

the linex= 1.

3. The endsof the
   graphhaveopposite
   behavior. Cubic
