Question 1055813
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.
