Find four relations from {a, b} to {x, y} that are not functions from {a, b} to {x, y}.

The answer is below.

Step-by-step explanation:

In order a relation from {a, b} to {x, y} to be a function, each element of {a, b} has to be mapped to one value in {x, y}.

{(a,x)} is not a function since the there is no relation defined from the element b of the set {a,b} to the set  {x, y}

{(b,x)} is not a function since the there is no relation defined from the element b of the set {a,b} to the set  {x, y}

{(a,x),(a,y)} is not a function since the element a of the set {a,b} is mapped two distinct element of the set  {x, y}

{(b,x),(b,y)} is not a function since the element b of the set {a,b} is mapped two distinct element of the set  {x, y}

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:
