Question

Determine which ordered pair is a solution of (y=x2+3) . (–3, 10), (2, 8), (3, 12), (5, 22) y=x2+3

Answer 1

Y = x² + 3      just put where it belongs to see which one is a solution to it.

10 = -3² + 3    (-3, 10)
10 = 9 + 3
10 = 12         not a solution because it doesn't equal the same in both sides.

8 = 2² + 3       (2, 8)
8 = 4 + 3
8 = 7             not a solution.

12 = 3² + 3     (3, 12)
12 = 9 + 3
12 = 12         a solution.

22 = 5² + 3     (5, 22)
22 = 25 + 3
22 = 28         not a solution.

so your answer is (3, 12).

hope this helps, God bless!
