Question 717728
I need to have a grasp on determining if a function is
------- 
injective: each domain value is mapped to an element in the image
space; but 1 or more of the image space values is not mapped to
(1,a),(2,b),(3,4) defined on A===>B
----------------------
surjective: at least one element of the domain is mapped to more
than one element of the image space
(1,a)(2,a)(3,b)(4,c) defined on A===>B
------------------------------- 
bijective: each domain value is mapped to an element in the image
space and each element of the image space is mapped to.
(1,a)(2,b)(3,c)(4,d) defined on A===>B

-------
Domain: A: {1,2,3,4} 
Image space: B: {a,b,c,d]
---------------------------------
