Consider the following set of ordered pairs of the elements of a set A = {1,2,3,4} of numbers and a set C = {a,b,c,d, e} of letters. {(1, a),(2,5),(3,c), (4, e)} Select all options true of this set. This is not a map from A to C. This is a map from A to C and is onto. This is a map from A to C and is one-to-one. This is a map from A to C and is neither one-to-one nor onto. Consider the following set of ordered pairs of the elements of a set B = {1,2,3,4,5} of numbers and a set C = {a,b, c, d, e} of letters. {(1, a),(2,b),(3,c),(4, d),(5, a)} Select all options true of this set. This is not a map from B to C. This is a map from B to C and is onto. This is a map from B to C and is one-to-one. This is a map from B to C and is neither one-to-one nor onto
