Given A a b c d e B 10 20 30 40 50 and F a function define

Given A = {a, b, c, d, e}, B = {10, 20, 30, 40, 50}, and F a function defined from A to B with F(a) = 50, F(b) = 10, F(c) = 30, F(d) = 10, F(e) = 40, find the image of {a, c, e}.

Solution

Image:

Let f :X Y and A X . As x moves about the set A , the set of values f( x) define the image of image of A .

So image of {a,c,e} is {F(a),F(c),F(e)} i.e.,{50,30,40}.
