Study for Friday's quiz (50 pts) on graphing

What you need to know for Friday’s mini quiz worth 50 points.

1)  Be able to sketch the graph of a parabola with no calculator, by finding its axis of symmetry, vertex, y-intercept, whether it has a max/min and how it opens, and its zeroes.

Ex:    f(x)= -x^2+2x+8

Axis of symmetry: _______

Vertex: ______________

Max/min open up/down: _________________

y-intercept:______________

zeroes:___________________

2)  Couple of wiggle graphs to sketch the graph of a function

Ex:  A) f(x)=(x^2-9)(x+4)(x-6)

       B) f(x)=2x(x^2+1)(x-2)^2(x+8)^3

3)  Determine the end behavior of the graph

Ex:  A) F(x)= x^4+3x^2-2x+7

        B)   f(x)=-2x^3_3x^2+8
