Graph the function using its vertex, axis of symmetry, and intercepts.
f(x) = x^2 - 6x
Complete the square on the x-terms:
x^2-6x+9 = y+9
(x-3)^2 = y+9
----------------
Vertex: (3,-9)
Axis of symmetry: x=3
------------
Intercepts:
y-intercept:
Let x=0, then y=0
------
x=intercepts:
Let x=0, then y = 0 or 6
