Question 37 Let A = {1, 2, 3}, B = {4, 5, 6, 7} and let ๐ = {(1, 4), (2, 5), (3, 6)} be a function from A to B. Based on the given information, ๐ is best defined as: (a) Surjective function (b) Injective function (c) Bijective function (d) function
Injective
Injective means one-one
Since all elements have unique image
โด R is injective
Surjective
Surjective means onto
Since all elements B do not have a pre-image
โด R is not surjective
So, the correct answer is (B)
