Question

The graph shows y as a function of x. Suppose a point is added to this graph. Which choice gives a point that preserves the function?

A (0, 9)(0, 9)
B (2, −4)(2, −4)
C (9, −1)(9, −1)
D (3, 5)

Answer 1

A

Explanation:

the other points have this problem : an x value has two y values so if added the graph will not represent a function
