# Let I z be the identity function defined on the set of all integers, and suppose that e , e i j k , K ( t ) , and u k j all represent integers. Find the following:a. l Z ( e ) b. l Z ( b i j k ) c. l Z ( K ( t ) ) d. l Z ( u k j )

To determine

(a)

Let IZ be the identity funciton defined on the set of all integers and suppose that e,b1jk,K(t),andukj all represent integers.

Find the value of

IZ(e)

Explanation

Given information:

IZ(e)

Concept used:

e Represent integers.

Calculation:

Since e represents the integer, then

To determine

(b)

Let IZ be the identity funciton defined on the set of all integers and suppose that e,b1jk,K(t),andukj all represent integers.

Find the value of

I(Z)(bijk)

To determine

(c)

Let IZ be the identity funciton defined on the set of all integers and suppose that e,b1jk,K(t),andukj all represent integers.

Find the value of

Iz(K(t))

To determine

(d)

Let IZ be the identity funciton defined on the set of all integers and suppose that e,b1jk,K(t),andukj all represent integers.

Find the value of

iz(ukj)
