The following ordered pairs (x, y) define the relation Q.

Q = { (-1, 4), (-2, 3), (4, 4), (2, - 2) }

Is Q a function?

a) no, because there is more than one x value from some y values

b) yes, because there is exactly one y value for every x value

c) yes, because there is exactly one x value for every y value

d) no, because there is more than one y value for every x value

Dashawn · Answer 1

A function is defined when there is exactly one y-value for every x value.

Thus, Q is a function (yes, because there is exactly one y-value for every x value)

We can conclude that (B) is the correct answer.
