A (1, 1), (2, 4), (3,6)
B (1,1),(3,9), (7,49)
© (1,2), (4,16), (8, 64)
D (4,8), (5, 25), (6,36)

Answer 1

B (1, 1),(3, 9), (7, 49)

Explanation:

Given function:

• y = x²

Let's verify which set of pairs are same with the given function:

A....................

• (1, 1) - yes
• (2, 4) - yes
• (3, 6) - no, 6≠ 3²

B....................

• (1, 1) - yes
• (3, 9) - yes
• (7, 49) - yes

C....................

• (1, 2)- no, 2≠ 1²
• (4, 16) - yes
• (8, 64) - yes

D....................

• (4, 8) - no, 8 ≠ 4²
• (5, 25) - yes
• (6, 36) - yes
