Can anyone help me thanks

C

Step-by-step explanation:

We can use the vertex form of a quadratic equation, given by:

Where a is the leading coefficient and (h, k) is the vertex.

We are given that the vertex is (-3, 1).

Hence, h = -3 and k = 1. By substitution:

Simplify:

With this, we can eliminate B and D.

Notice that our parabola is curving downwards.

Therefore, our leading coefficient must be negative.

The only choice that leaves us with is C.

So, our function is:

And our final answer is C.
