1.for x=2 and x=4 , y=0 so  the zeroes are 2 and 4

the symettry of the parabola is x=3

2. the answer is x= -b/2a=-2/2=-1

x=-1 is the symettry of the parabola

3. V(-b/2a, -(b^2-4ac)/4a)

-b/2a=-10/4=-5/2=-2.5

- (b^2-4ac)=- (100-64)=-36

4a=4*2=8 so the answer is V(-2.5 , - 36/8)= V(-2.5, -4.5)

4. y=3x^2-18x+17

V(-b/2a, -(b^2-4ac)/4a)

  V(18/6, (-18^2+4*3*17)/12)

   V(3, (-324+204)/12

   V(3, -10)

the simmetry of parabola is x=3
