Exersice 2.3.16 : Let f and g be the functions defined by f(x) = x - 4 and g(x)= x .Find the functions f + g , ƒ -8 and find their domains.

(a) Let A = B = {a, b, c, d}. The function f is defined from A to B which is given below: f = {(a, a), (b, c), (c, b), (d, b)} Find the domain and range of the function. Hence determine whether the function is everywhere defined, onto and one to one. Explain your answers. (6 marks)
