algebra precalculus - Hello i am confused with this quadratic question.

Why is it that when we look at equation for example $(x-2)^2+5$ and the question states "state the minimum point" the minimum point is $5$.

I get that the coordinates of minimum point is $(2,5)$ but why is only $y$ taken into consideration. Also if there is equation like $2(x-2)^2+5$ would the minimum point still be $(2,5)$?

please can you reply back to me as soon as possible as my exam is in few days and I really want to understand maths rather than "memorise it".
