Question 1166392
Come up with any 6 pairs of ordered coordinates.

i.e. (x,y) = (1,2), (2,3), (3,4), (4,5), (5,6), (6,7) 

a.) Plot these coordinates:

It will look like this (without the line)

{{{ graph( 300, 200, 0, 7, -10, 20, x+1) }}}

b.) Very simply:

 [1] --> [2]
 [2] --> [3]
 [3] --> [4]
 [4] --> [5]
 [5] --> [6]
 [6] --> [7]
c.) Do any of the x values repeat? In this case, no. Therefore, it is a function.

d.) Domain is all your x values (1,2,3,4,5,6). Range is all your y values: (2,3,4,5,5,7)
