The temperature of a point [MATH](x,y)[/MATH] in the plane is given by the expression [MATH]x^2 + y^2 - 4x + 2y[/MATH]. What is the temperature of the coldest point in the plane?
I got a circle with the radios of [MATH]\sqrt5[/MATH] with a Centerpoint at [MATH](2,-1)[/MATH] but I don't know how they want me to give my answer, or how temperature comes in and what would be the "coldest". could someone please help, thanks.
