Question

Which set of ordered pairs represents a function? {(9.1).(-6.3), (0.-4), (9,-1)} {(-4,4),(6,4), (6,-5),(0,8)} O {(4.4).(0.-6).(3,4).(-5, -1)} O {(-1,3), (9,-7), (2,4), (9,5)} Submit Ang

Answer 1

Given a set of ordered pairs, it will represent a function if all the x-components of each ordered pair are different. In this case, the only set that has all x-components of eac ordered pair different is:

`\mleft\lbrace(4,4\mright),(0,-6),(3,4),(-5,-1)\}`
