Tell whether each pairing of numbers describes a function.If so identify the domain and the range.If not,explain why. 0,0 1,-1 2,-2 3,-3 4,-4 5,-5 6,-6 7,-7 8,-8 and 9,-9

Answer 1

This is a function, there are no repeating x values.

Domain (x values): {0,1,2,3,4,5,6,7,8,9}

Range (y values): {0,-1,-2,-3,-4,-5,-6,-7,-8,-9}
