Maximum value is infinity, since for very large x this function grows to infinity.

Since the coefficient of the xterm is positive, this is the graph of a parabola opening upward toward +infinity.
 
Vertex
x = -b/(2a) = -2/(2)(1) = -2/2 = -1
y = f(-b/(2a)) = f(-1) = 9.
 
Vertex
(-1, 9)
 
 
Minimum value would be 9.
