how would you figure out this problem? dont give the answer give how to do it, pls.

The range means what are the y values for the set of ordered pairs.
The range is {2, 4, 6}
The range is {2, 4, 6}

The assumption is this:
{(x, y), (x, y), (x, y), (x, y)} where Sx ={1,2,3,4} and Sy={2,4,2,6} [meaning the set of all numbers x and the set of all numbers y]; and, f(x)=y (meaning y is a function of x). If you plot the numbers in a Cartesian coordinate field, then your range is the y interval and your domain is the x interval. For the range of the set, take the largest of the y values and subtract the smallest y value. For the domain, do the same for the x values. This works because subtracting the numbers is used to find the distance between them.

Look at all the possible y-values. That's the range.
Here it's 2,4,6
Here it's 2,4,6

{(1, 2), (2, 4), (3, 2), (4, 6)}
range: {2, 4, 6}
range: {2, 4, 6}
