Determine whether the given quadratic function has a minimum value or maximum value. Then find the coordinates of the minimum or maximum point.
f(x) = x2 + 2x - 9
Coefficient of the x^2 term is +, --> a max
The vertex is on the LOS, Line of Symmetry, which is
x = -b/2a
x = -2/2
x = -1
-----
Vertex at (-1,f(-1))
