Plugging into the Given Formula the value of y:
Multiply the left side:
Add 14 to both sides to get:
Divide both sides by 8 and we get:
Therefore, x=7 and the proof is complete
I hope this helps you

I haven't learned this is class yet, but I had a bf that taught me this
The following are the answers to
the questions presented:
Part 1:
Vertex: <span>(<span><span>−3</span>/ 2</span>,<span> 11/2</span>)</span>
Axis of
symmetry = x = -3/2
Domain = all
real numbers
Range = <span>y </span><span>≤ </span>11/2
Part 2:
A quadratic equation is symmetrical around its vertex. The
equation for the axis of symmetry is x = -3/2 since the equation is in terms of
x. Since no value of x is undefined, then the domain of the equation is clearly
all real numbers. Since the value of “a” is negative, then that means the y
coordinate of the vertex is the maximum value so the range will never get above
11/2. I am hoping that these answers have satisfied your queries and it
will be able to help you in your endeavors, and if you would like, feel free to
ask another question.
Since A = bh
and A = 198 and b = 18?
h = A/b
= 198/18
= 11
