The crest of this parabola is at (3,5) when the y-value is 6 the x value -1 what is the coefficient that the squared hatchet in the

**positiveeast.org:**

1/16

**Step-by-step explanation:**

Here,

Vertex =(3,5)

x= -1, y=6

Simply,eqn that parabola is given by ax^2+bx+c=y

So, coefficient that squared hatchet (x^2) is **"****a****"**

Therefore, we"ve to discover the value of **a**

Moving on to solution:

a-b+c=6 ___(i) (**by**** ****putting**** ****the**** ****given**** ****values**** ****of**** ****x**** ****and**** ****y**** ****in**** ****eqn**** ****of**** ****parabola**** **)

We know that,

Vetex=(-b/2a, ( 4ac-b^2)/4a)

(3,5) = (-b/2a , (4ac-b^2)/4a)

Equating equivalent sides,we get

3= -b/2a

b=-6a___(ii)

Again,

5=(4ac-b^2)/4a

5=(4ac/4a) - (b^2/4a)

5= c- (36a^2/4a) (**by**** ****putting**** ****value**** ****of**** ****b**** ****from**** ****eqn**** ****ii**** **)

5= c-9a___(iii)

Now,moving back to the an initial eqn

a+6a+5+9a=6

16a=1

therefore,a=1/16

Hence ,the compelled value that coefficient that squared term is 1/16.
