Question

(a) Let R = { (, ) ∶ x and y are integers and x

2+ y

2 = 64} Write domain and range.



please help i need full solution​

Answer 1

Answer:

We have, R2 = {(x, y) | x and y are integers and x2 + y2 – 64}

Clearly, x2 = 0 and y2 = 64 or x2 = 64 and y2 = 0

x = 0 and y = ±8

or x = ±8 and y = 0

R2 = {(0, 8), (0, -8), (8,0), (-8,0)}
