Make a table of values to graph each function rule. Is the graph continuous or discrete? Justify your answer.

Question

The cost (C) for baseball tickets, in dollars, depends on the number (n) of tickets bought, as related bt the function rule C=16n. Make a table of values to graph each function rule. Is this graph continuous or discrete? 

Answer 1

This is a discrete graph (points but no connections between them), because you cannot buy 1/2 a ticket. There are discrete values (C's) that correspond to 16 times the number of tickets purchased. 

C = 16n 

n(tickets)         C(cost)  

  1                      16

  2                      32

  3                      48

  4                      64

  5                      80
