Answer:
This is a function and there is no value of x for which we will get two or more different values of y.
Explanation:
A relation contains the points (-5,-10), (-2,-4), (-1,-2), (4,8), and (5,10).
So, if we want to model the equation that includes those points then we will get the equation of a straight line passing through the origin {Since the rate of change of y with respect to x is uniform.
The equation is y = 2x
Now, this is a function and there is no value of x for which we will get two or more different values of y. (Answer)
