Answer:
d does not have an inverse image 
Step-by-step 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
