B. (-7/2,195/4)
C. (7/2,-37/4)
D. (7/2,-97/4)
E. (6/7,330/49)

Answer 1

Do you know how to find the vertex?
Hint: -b/2a ?

Answer 2

-(-7)/2(1)=7/2
am i correct?

Answer 3

Yes.
This gives us that.. .?

Answer 4

its for x axis..how bout y axis?

Answer 5

now plug in x=7/2 in f(x)=x^2-7x+12
to get your 'y' value :)

Answer 6

yaa thank you i gt -1/4 @hartnn n @saifoo.khan

Answer 7

thats correct :)
