Answer:
The function which represents the graph is:

Hence, option B is correct.
The graph is also attached.
Step-by-step explanation:
From the graph, it is clear that:
The vertex = (2, 3)
The y-intercept = (0, -1)
Let us check the equation

Determining the y-intercept:
The value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
substituting x = 0 in teh equation





Thus,
The point representing the y-intercept is: (0, -1)
Determining the vertex:
The vertex of an up-down facing parabola of the form ax² + bx + c is:

As the equation is

Rewriting the equation
in the form ax² + bx + c:

The Parabola params are:

Thus,



Now plug in
in the equation to find 




Therefore, the vertex of the equation is: (2, 3)
Hence, the function which represents the graph is:

Hence, option B is correct.
The graph is also attached.
