Step-by-step explanation:
factor out the x^2-6x+9
which would be (x-3)^2
that means (x-3)(×-3)
you can find the two sides of this parabola by making each parathese equal to 0
like x-3=0, x-3=0
then solve the equation
x=3, x=3
since parabolas are symmetrical you add the two 3s and divid it in half to find the middle/reflection line
3+3=9 9÷2=4.5
x=4.5, y=0
(0,4.5)
