Question 31463
a) y=(x^2-4x   )-5
Complete the square:
y=(x^2-4x+4)-5-4
y=(x-2)^2-9

b)The line of symmetry is x=2

c) Draw the line of symmetry.
   When x=2, y=-9; plot the point (2,-9)
   That is the vertex of the parabola.
   The y=intercept is (0,-5); plot it.
   Draw the parabola which opens up.

d) The (x-2) moves y=x^2 two units to the right.
   The "-9" moves the parabola nine units down.
