Question

Determine whether the relation is a function. c = {(10,3), (-10, – 3), (2, - 2). (3,- 10)}

Answer 1

set x to set y to be a function if each member of set x pairs is exactly one member of set y

set x: 10, -10, 2, 3

set y: 3, -3, -2, -10

so the relation is a function

Answer 2

Yes, it is a function, because no x value is repeated.
