Question

Is (3, 7) a solution to x² + 1 = y ?

Answer 1

No

Explanation:

To know if (3, 7) is a solution, plug 3 into the x and 7 into the y.

`(3)^(2) +1=7`

9 + 1 = 7

`10\\eq 7`

Therefore, (3, 7) is not a solution.

Answer 2

No

Explanation:

3² + 1 = 7? Nopeeeee

3 * 3 = 9, that alone is bigger than 7.

3 * 3 + 1 = 10.

10 is bigger than 7.
