Answer 2

Answer:

The values are a = 7 , b = 7

Step-by-step explanation:

If M is a set the Identity function f on M is a function which satisfies the condition f(x) = x for all elements x in M.

In otherwords the function value f(x) in the codomain M is always same as the preimage x in the domain M.

Therefore in the Identity function image is same as the input element.

Given identity function is {(a , b), (7, b)}

Since this is the Identity function,

a = b and 7 = b

a = b = 7

Therefore values are a = 7, b = 7
