we know that
the equation
describe a vertical parabola with vertex at point 
if 
-------> the parabola open Up and the vertex is a minimum
if 
-------> the parabola open Down and the vertex is a maximum
in this problem we have
---> because is positive (given problem)
so
The vertex is a minimum
therefore
<u>the answer is the option C</u>
Up
I don't understand or see for the matter the question what is it
