General Forms of a Sequence

General Forms of Sequence

 

 

 

Geometric Sequence- has a common ratio

ex. an = a1 x rn-1 -----> 3 , 6 , 12 , ___ ---> a4 = 3 x 23

a4 = 24

Arithmatic                      
an = a1 (n-1) d

*ex. 1, 3, 5, 7, 9    ( increasing 2)

Geometric
an = a1 x rn-1

*ex. -9, 3, -1. 1/3. -1/9 (multipying by -1/3)

Charactoristics & Traits of a Graph

Charatoristics & Traits of a Graph

I. Domain- left and right traits of a graph

                                                   Range- up and down traits of a graph

    

     II. End Behaivor-

                Left: x approaches negative infinity   Up: y approaches positive infinity

                Righ: x approaches positive infinity   Down: y approaches negative infinity

   

     III. X / Y Intercept

                x intercept: where it crosses x-axis {ex. (3,0)}

                y intercept: where it crosses y-axis {ex. (0,3)}

     IV. Function- passes the Vertical line test.
         One to One- passes the Horizonal and Vertical line test.

     V. Symmetry-
               even- symmetric about the y-axis
               odd- rotational symmetry around the origin
               niether- none at all

     VI.  Max/Min
          MAX- graph opens down            Absolute- 1 single point
          min- graph opens up                    Local- more than one single point
