1 answer

To find the range of a set of numbers, you subtract the smallest number from the largest number.

Given the set of numbers: 3, -9, 7, -1, 5, -4, 2

  1. The smallest number is -9.
  2. The largest number is 7.

Now, calculate the range:

Range = Largest number - Smallest number
Range = 7 - (-9)
Range = 7 + 9
Range = 16

Therefore, the range of the set of numbers is 16.
