The range of the following relation r {(3,-2), (1, 2), (-1, -, 2)} is
a.{-1, 1, 3}
b.{-1, -1, 1, 3} ♡
c.{-4, -2, 2, 2}
d.{-4, -2, 2}

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
