We are given the graph of a parabola with a shaded portion, representing the inequality.

We can see that the parabola opens up rather than down, so we can instantly eliminate options C and D.

When f(x) is greater than the expression, the area within it is shaded.

Answer choice B best represents this.

Answer:

The answer to your question is the second option f(x) ≥ 2x² + 4x

Step-by-step explanation:

In the graph, we observe that we need the up area of the parabola so the inequality must be ≥. From this observation, we discard the options one and three.

The last equation is a parabola that opens downwards not upwards as we notice in the graph so we discard the fourth option.
