Homework Statement
Use technique of completing squares to Show that this function has an absolute minimum.
f(x, y) = x^2 + y^2 − 2x + 4y + 1
Homework Equations
Not entirely sure how completing the squares will indicate an absolute minimum.Is there some additional reasoning required?
The Attempt at a Solution
Having completed the square i arrived at this equation.
(x-1)^2 +(y+2)^2 = 4
Again,all i can extrapolate from this is the center point of an obvious circle of radius 4.
