y = 2(x - 3)^2 - 4
This is a quadratic function in the form y = a(x - h)^2 + k, where (h, k) represents the vertex of the parabola. In this case, the vertex has coordinates (3, -4).
Since the coefficient of the squared term (2) is positive, the parabola opens upwards, indicating that the vertex represents the minimum value of the function.
So, the correct response is:
Minimum value: -4
Domain: all real numbers
Range: all real numbers greater than or equal to -4
