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

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