Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one.

azamat

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above:

- The<span> room has square dimensions and it has been built with two pieces of sheetrock, a smaller one and a larger one.

2. Therefore, let's call

x: the smaller one.
y: the larger one.

3. Then, you have that the lenght of the wall is the sum of the smaller one and the larger one:

x+y

4. So, the area of the room is:

(x+y)(x+y)
(x+y)</span>²

Therefore, the answer is: (x+y)²

Answer:

Part 1) The domain of the quadratic function is the interval (-∞,∞)

Part 2) The range is the interval (-∞,1]

Step-by-step explanation:

we have

$f(x)=-x^2+14x-48$

This is a quadratic equation (vertical parabola) open downward (the leading coefficient is negative)

step 1

Find the domain

The domain of a function is the set of all possible values of x

The domain of the quadratic function is the interval

(-∞,∞)

All real numbers

step 2

Find the range

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

we have a vertical parabola open downward

The vertex is a maximum

Let

(h,k) the vertex of the parabola

so

The range is the interval

(-∞,k]

Find the vertex

$f(x)=-x^2+14x-48$

Factor -1 the leading coefficient

$f(x)=-(x^2-14x)-48$

Complete the square

$f(x)=-(x^2-14x+49)-48+49$

$f(x)=-(x^2-14x+49)+1$

Rewrite as perfect squares

$f(x)=-(x-7)^2+1$

The vertex is the point (7,1)

therefore

The range is the interval

(-∞,1]
