Question

For each relation, decide whether or not it is a function. Relation 1 Domain Range cloud -> -5 paper -> 5 door -> -1 pencil -> -6 Function Not a function Relation 2 Domain Range -5 -> -8 5 -> -2 -1 -> -8 -6 -> 4 -8 -> -8 Function Not a function Relation 3 {(r, u), (u, x), (r, n), (u, r)} Relation 4 {(3, t), (-2, t), (3, b), (7, d)}

          For each relation, decide whether or not it is a function.
