Question

If P= {9, 4, 25} and Q = {2, 3, 5, -2, -3, -5}, R is defined from P to Q by

R = {(x, y): x = y2

, x ∈ P, y ∈ Q}

(i) Write the relation in Roster form.

(ii) Draw the arrow diagram of the above relation.

(iii) What is its domain, range and co-domain?​

Answer 1

Answer:

The given relation R is from a set P to Q. where P = { 9,4,25} and Q = { 5,3,2,1,-2,-3,-5}

Defined as R ={ (9,3), (9,-3), (4,2),(4,-2), (25,5),(25,-5)}. Write this relation in i) Set

builder form ii) arrow diagram? What are its domain and range
