Notice that the value of "x" (first coordinate in the pairs we are given differ from each other in a constant of 4 units:
-1 + 4 = 3
3 + 4 =7
7 + 4 = 11
Now when we analyze the y-values for the pairs, we see that there is no constant value added, since:
from 3 to 6 (there are 3 units)
from 6 to 10 (there are 4 units)
from 10 to 15 (there are 5 unis)
I am going to try to plot the points and find which type of curve better fits them.Please give me a few moments for the plotting.
