You can
put this solution on YOUR website!is the following relation a function? Explain Please.
(1,2),(2,3),(2,5),(2,7)
-----------
Points 2, 3 and 4 are colinear, on a straight line x = 2, and fit a simple function.
----------
The first point is not on the line.
A function can be found that passes thru all 4 points, but it will be complex, I think 4th order or higher, or a sinusoid.
A yes or no answer depends on what level of functions are acceptable.
