Question

Which inequality below is represented by the following graph: A. y < -2x² + 10z - 8 B. y 2x² + 10x – 8

Answer 1

Explanation

We are required to determine the inequality that satisfies the given graph.

This is achieved thus:

We can deduce from the graph that the curve drawn is not a broken line. Therefore, it cannot be strictly greater than or strictly less than.

We know that only "true" region is shaded. By testing the origin, we can deduce that the correct inequality is:

`y\geqslant-2x^2+10x-8`

Hence, the answer is:

Option D
