Question

Given that x is an integer, state the relation represented by absolute value y = x/2 and 0 is less than or equal to x which is less than or equal to 2 by listing a set of ordered pairs. Then state whether the relation is a function. Write yes or no.

Please help--no clue what to do!

Answer 1

abs (x/2) is postive, so it is greater than zero. To be less than 2, that puts constraints on x, for instance, x cannot be six.

Answer 2

So a set of ordered pairs could be
(3, 3/2) and it would be a function.
