Answer:
a = 19
Step-by-step explanation:
If the rate of change is -8, subtract 8 from your y value of 27. And if 19 is correct, you should be able to subtract 8, and get 11 as the next number in the function, which you do, so 19 is the value of a.

Answer:

Step-by-step explanation:
The complete question is shown in the attachment.
The length of the rectangle is x + 12. The width of the rectangle is x + 3.
Recall that area of a rectangle is 
In terms of x, the area is 
Recall the distributive property of real numbers: 
We apply this property to get:

We expand again to get:

We now simplify to obtain:

The area of the rectangle is 
we are given
graph of a quadratic function
Quadratic function:
Those function which has degree=2
we can write it as

Since, the degree is 2
so, the shape of the curve will be parabolic
so, option-B.........Answer
