Answer:

[tex]y=-5(x-4)^2+4[/tex]

Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y=a(x-h)^2+k[/tex]

Where (h, k) is the vertex of the parabola, and a is a coefficient different from zero.

The vertex is located at (4,4).

Substituting the coordinates of the vertex, the equation of the function is:

[tex]y=a(x-4)^2+4[/tex]

The value of a will be determined by using the given point (3,-1).

[tex]-1=a(3-4)^2+4[/tex]

Operating:

[tex]-1=a(1)+4[/tex]

Solving:

[tex]a=-5[/tex]

The equation of the graph is:

[tex]\boxed{y=-5(x-4)^2+4}[/tex]
