The absolute minimum of <img src="https://tex.z-dn.net/?f=f%28x%2Cy%29%20%3D%20x%5E%7B2%7D%20%2B%204y%5E%7B2%7D%20-4y" id="TexFo

On the line segment x=2, f depends only on y :

f(2,y) = g(y) = 4y^2 - 4y - 4

Find the critical points of g.

\dfrac{dg}{dy} = 8y - 4 = 0 \implies y = \dfrac12

At this critical point, we have

g\left(\dfrac12\right) = f\left(2,\dfrac12\right) = 3

Check the value of f at the endpoints of the line segment.

f\left(2,0\right) = 4

f\left(2,2\right) = 12

So we have

\min\left\{f(x,y) \mid x=2 \text{ and } 0 \le y \le 2\right\} = \boxed{3} \text{ at } (x,y) = \left(2,\dfrac12\right)

Therefore the best option is Median
