Question 51704: The number of song requests a radio station receives per day is indicated in the table below. construct a graph for this data.
x 8 9 10 11 12
0.21 0.31 0.16 0.14 0.18
I'm not sure if I can graph with the bottom numbers or if I have to use the formula n*p and then graph....the book doesn't have a good example. Thanks for your help

The number of song requests a radio station receives 
per day is indicated in the table below. construct a graph 
for this data. 

x  8   9   10   11   12
0.21 0.31 0.16 0.14 0.18

You have to give more information so I can help you better.  I can't tell
whether you are taking algebra of statistics.  Maybe your teacher wants 
you to just connect the points with straight lines, like this

In this graph, consider the y-axis to represent hundredths, not the whole
numbers written on the y-axis (example, 16 on the y-axis means 0.16)

Perhaps you need the best-fitting cubic graph for this.  If so it is

y = .026583x³-.77439x²+7.62588x-24.455

If you are studying regression, or just linear regression, post again and
I can help you further.
