You can put this solution on YOUR website! determine wether the data set could represent a linear function. Why or why not? explain the reason as well.
x | f(x)
0 | -2
1 | 0
2 | 2
3 | 4
===============
If you plot the 4 points, you see they're colinear, ie, on the same straight line.
line --> linear
=============
If you pick any 2 points, you find the slope of the line thru them has the same slope.
===> it's a function.
