Removing (b) (-2, 1) would make the graph a function of x
Removing which point from the coordinate plane would make the graph a function of x?
From the question, we have the following parameters that can be used in our computation:
(–4, 3) (–2, 1) (0, 4) (1, 1) (-2, -3)
In order for a relation to be a function, each input value (x-coordinate) must correspond to exactly one output value (y-coordinate).
This means that no two different points can share the same x-coordinate.
Looking at the x-coordinates, we see that
x = -2 have the y values y = 1 and y = -3
This means that removing (-2, 1) or (-2, -3) would make the graph a function of x
