Question 6 • [INMT3] Integrated Math 3 Sem 1 (26-27)

Select all of the ordered pairs that make the inequality y > x2 + 3x – 4 true.

Answer
A
(0, 0)
B
(2, 1)
C
(–2, –1)
D
(–5, –1)

Explanation

Substitute each pair’s x-value into y > x² + 3x − 4, then check whether its y-value is greater than the result. For (0, 0), the right side is −4, and 0 > −4, so the inequality is true. For (−2, −1), the right side is 4 − 6 − 4 = −6, and −1 > −6, so it is also true. The other two pairs do not satisfy the inequality.
