Thank you!
This is not from a book. It was a worksheet given to me.

Simply plot the points given. The domain is the set of all x values while the range is the set of all y values of the given points. So we get:

Domain: {0, 2, -4}

Range: {0, 4}

Take note that each value of 'x' only maps to one 'y' value. So this means that the relation is a function.
