Resposta

The correct answer is B: \(f(x) = -2x^2 + 12x - 12\).

Explicação

## Step 1The vertex form of a quadratic function is given by the formula:### \(f(x) = a(x-h)^2 + k\)where \((h, k)\) is the vertex of the parabola.## Step 2Given the vertex \((3,6)\), we can substitute these values into the formula to get:### \(f(x) = a(x-3)^2 + 6\)## Step 3We also know that the function passes through the point \((4,4)\). Substituting these values into the equation, we get:### \(4 = a(4-3)^2 + 6\)## Step 4Solving the equation for , we find that .## Step 5Substituting back into the equation, we get:### \(f(x) = -2(x-3)^2 + 6\)## Step 6Expanding and simplifying this equation, we get:### \(f(x) = -2x^2 + 12x - 12\)
