Find the range of {(3.2, –3), (7.6, 5.9), (1.4, –3), (–9.1, 8.3)}.
{–3, 1.4, 3.2}
{–9.1, 1.4, 3.2, 7.6}
{–9.1, 5.9, 7.6, 8.3}
{–3, 5.9, 8.3}

[-3, 5.9, 8.3}

Step-by-step explanation:

The range is all the y-values.

So since we are given a list of coordinates (x,y), we can take the y-coordinate from each (2nd number in each coordinate) and make a list of the range. We don't need to list repeated values.
