Explanation:

The vertex form of a quadratic function directly reveals the vertex, which for a parabola opening upwards (the case when finding a minimum) gives the minimum value as the y-coordinate of the vertex. This form allows for immediate identification of the minimum without additional calculations, making it the most efficient choice.

Answer:

The vertex form of a quadratic function, written as $f(x)=a(x-h)^2+k$ where $(h,k)$ is the vertex. The minimum value of the function is $k$, which is directly visible in this form.
