Compound function

Let's look at an example to understand what a composite function is. Consider the sets: A = {- 2, -1,0,1,2} B = {- 2,1,4,7,10} C = {3,0,15,48,99} And the functions: f: AB defined by f (x) = 3x + 4 g: BC defined by g (y) = y 2 -1 As shown in the diagram above, for all x A we have a single y B such that y = 3x + 4 , and for all y B there is a single z C such that z = y 2 -1.
