Answer:

The answer to your question is Letter C

Step-by-step explanation:

Data

Vertex (4, -3)

Process

From the image, we notice that it is a horizontal parabola that opens to the left.

So, it formula must be          (y - k)² = 4p(x - h)

-Substitute the vertex

                                             (y + 3)² = 4p(x - 4)

Consider 4p = 1

                                             (y + 3)² = x - 4

Solve for x

                                             x = (y + 3)² + 4

Solution

Letter C
