What is the domain and range? {(4,2), (-9,2), (5,4), (4,17)}

The domain is all of the possible x values.

The range is all of the possible y values.

When writing the coordinates for a point, we know it should be in this format: (x,y).

Thus we get:

Domain = {-9,4,5}

Range: = {2, 4, 17}

(TIP: do not repeat any values. Only write each number once.)

(TIP: Order the values from least to greatest.)
