certainly not linear, slopes between pairs of points would have to be the same, --- they are not.
Took differences in the y values up to the fourth difference columns. No constant
so , no polynomial up to 4th degree.
Not even Wolfram found an equation, when to least-fit equations.
http://www.wolframalpha.com/input/?i=equation%7B+(0,-1),+(1,0),+(2,3),+(3,6),++(4,15)%7D
The ordered pairs represent a function (0,-1). (1,0), (2,3), (3,6), and (4,15)
a. graph the ordered pairs and describe the pattern. Is the function linear or nonlinear?
I said nonlinear.
b. Write an equation that represents the function.
I don't know what the slope would be, what I have right now is
y=?-2
Thank you!
