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

Since the coefficient of the x

^{2 }term 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.
