MULTIPLE CHOICE QUESTION

What is the range of this function. Remember...we are looking for only the y coordinate values of these points.
{-4, -1, 2, 3}
{-5, -4, 2, -1}
{-5, -2, 1, 4}
{-5, 3, -2, -4}
Answer explanation
I would have looked at the points from bottom to top, remembering that the coordinates are in the format (x,y). Range is the set of y coordinate values.

MULTIPLE CHOICE QUESTION

This is not a function. Which point can you remove from the list below such that the remaining points would form a function? Remember...we are looking at x-values. You may use the "vertical line test" too. Hint...we want to remove one point that shares an x-value with another point.
(1,3)
(3,3)
(-2,-3)
(4,-1)
Answer explanation
The relation is not a function because it assigns multiple outputs to at least one input. The domain is {-5, -2, 2} and the range is {-4, 1, 3}, confirming the correct choices.
