Answer 2

Answer:

hello there,,,,, here is your solution

Step-by-step explanation:

A= {a, b} and B= { x, y, z}.........(given)

Number of relations =2(raise to number of

from B to A. elements in B by A)

= 2 (raise) n (B) into n (A)

Since,

number of elements in set A= 2

number of elements in set B= 3

Number of

relations from B to A= 2 raise to n(B) into n(A)

= 2³×² (multiply this)

Hope this helps you
