Question

Which of the following points is in the solution set of y > -x2 + 5? (0, 5) (1, 3) (2, 4)

Answer 1

(2, 4)

Explanation:

The only point that satisfies the inequality is (2, 4).

(0, 5) : -0^2 +5 = 5 . . . . . not > 5

(1, 3) : -1^2 +5 = 4 . . . . . . 3 is not > 4

(2, 4) : -2^2 +5 = 1 . . . . . . 4 is greater than 1, so this point is in the solution set.
