There are24 and 40 students the ratio 4:7 how many students are in the class

Option A.

Step-by-step explanation:

Vertex form of a parabola passing through vertex (h, k) is represented by

y = (x - h)²+ k

where (h, k) is the vertex.

From the given graph vertex of the given parabola is (-1, -4)

Now we will replace these coordinates in the equation given above.

y = (x + 1)² - 4

Therefore, the given equation matches with option A.
