The distance is
Explanation:
The easiet way is graphically.
Plot the parabola and the point and you will see the shortest distance
graph{(y-16+x^2)((x-4)^2+(y-16)^2-0.2)=0 [-22.2, 29.12, -6.27, 19.4]}
From the graph, you can see that the point
The distance is
The vertex form of a parabola is
Here, we have
As
If you need, I can calculate the shortest distace with partial derivatives.
