Answer:
A
Step-by-step explanation:
We are given the function:
And we want to determine its graph.
One of the most important features of a quadratic is its vertex. So, we can start by finding the vertex using the formulas:
In this case, <em>a</em> = 1, <em>b</em> = -6, and <em>c</em> = -7.
Find the <em>x-</em>coordinate of the vertex:
Substitute this back into the equation to find the <em>y-</em>coordinate:
Therefore, our vertex is at (3, -16).
The only graph whose quadratic's vertex is at (3, -16) is Graph A. Thus, our answer is A.

We have to calculate the area of a rectangular quilt.
area of a rectangle=length x width
Data:
length=60 in=60 in(1 foot/12 in)=5 ft
width=40 in=40 in(1 foot/12 in)=3.33 ft
Area of the rectangula quilt=(5 in)(3.33 in)=16.67 ft²
Now, we have to calculate the cost of this quilt
$1.50-----------------1 ft²
x------------------------ 16.67 ft²
x=($1.5 * 16.67 ft²)/1 ft²=$25
Answer: the cost of the rectangular quilt was $25
