The Answer of suppose g: A → B and f : B → C where A = {1, 2, 3, 4}, B = {a, b, c}, C = {2, 8, 10}, and g and f are defined by g = f(1, b), (2, a), (3, b), (4, a)g and f = {(a, 8), (b, 10); (c, 2)}.
-$$\text { Find } f \circ f ^ { - 1 } \text {. }$$

Suppose G: a → B and F : B → Find f∘f−1. \text { Find } f \circ f ^ { - 1 } \text {. } Find f∘f−1.

Suppose G: a → B and F : B → $\text { Find } f \circ f ^ { - 1 } \text {. }$
