You can put this solution on YOUR website!
f(x)= (x-3) (x+2)
f(x) = x^2-x-6
a = 1
b = -1
c = -6
------------------
Find:
Axis of symmetry: x = -b/(2a) = 1/2
-----------------------
Vertex: (-b/2a ; f(-b/2a)) = (1/2 , (1/4)-(1/2)-6) = (1/2,-25/4)
--------------------------
Y-intercept:: f(0) = -6
----------------------------------
Max or Min: Min value = f(1/2) = -25/4
