Question

Let A (10, 11, 12, 13 and B (a, b, c, d) Let g be a function from A to B defined by f(10, a), (11,a), (12, b), (13,b)) What is the inverse image of d?

Answer 1

d does not have an inverse image

Explanation:

From the question we are told that

The first set is A (10, 11, 12, 13 )

The second set is B (a, b, c, d)

The function that from A to B is f(10, a), (11,a), (12, b), (13,b))

Generally for a function defined by (x,y), y is the image of x while x is the inverse image of y

Now considering the function we are given and the value d we see that and inverse image is not defined for d in the function

hence d does not have an inverse image
