Question

Figure shows a relation between set P and Q. Write the relation R

• A. R = {(9, 3), (9, -3), (4, 2), (4, -2), (36, 6), (36, -6)}
• B. R = {(9, 1), (9, 2), (9, 3), (9, 4), (9, 5), (9, 6)}
• C. R = {(9, 3), (9, -3), (4, 2), (4, -2), (25, 5), (25, -5), (36, 6), (36, -6)}
• D. R = {(1, 7), (2, 4), (-2, 4), (3, 9), (-4, 16), (4, 16)}

Answer 1

The correct option is C

R = {(9, 3), (9, -3), (4, 2), (4, -2), (25, 5), (25, -5), (36, 6), (36, -6)}

The Relation R is "x is the square of y”

x = $y^2$

R = {(x, y): x is the square of y x $\in$ P, y $\in$ Q}

R = {(9, 3), (9, -3), (4, 2), (4, -2), (25, 5), (25, -5), (36, 6), (36, -6)}
