The function f is given in three equivalent forms.
Which form most quickly reveals the vertex?

Option B is the correct option.

Step-by-step explanation:

We know that the vertex form of a quadratic's equation is generally expressed as

y = a(x - h)² + k

where (h, k) is called the vertex of the quadratic function

In our case, given the function

now comparing the equation with y = a(x - h)² + k

Here:

h = -3

k = 25/2

Therefore, the vertex of the function is:

(h, k) = (-3, 25/2)

Thus,

The    form most quickly reveals the vertex.

Hence, option B is the correct option.
