URGENT, will reward brainliest. Determine the equation of the graph and select the correct answer below.

PilotLPTM [1.2K]

In this problem, it will be helpful to know the vertex form of a parabola, which is listed below:

$y = a(x - h)^2 + k$

$a$ is a constant which helps to determine whether the parabola opens up or down. If $a < 0$ , then the parabola opens downward and if $a > 0$ , the parabola opens upwards
$(h, k)$ is the vertex of the parabola

By looking at the graph, we can first see that the graph opens downwards, meaning that $a < 0$ . Thus, choices C and D are not valid. Now, let's use the vertex of the parabola to complete the equation.

The vertex of this parabola is (-1, 3), as shown by the graph. When we substitute this into our formula, we get:

$y = -(x + 1)^2 + 3$
