If f = { (4, 2), (6, 1), (8, 4), (10, 2), (12, 5) }, what is the range?

{1, 2, 4, 5}

all whole numbers

{2, 1, 4, 2, 5}

{4, 6, 8, 10, 12}

Given the function:

f = { (4, 2), (6, 1), (8, 4), (10, 2), (12, 5) }

the range is all the y-values, it's not to be confuse with the domain which is all the x-values, thus the range of our function will therefore be the following set.

{2,1,4,2,5}

Answer:

{2,1,4,2,5}
