Analyze the key features of the graph of f(x) shown below. Use rules of transformations and the parent function to formulate an

sweet [91]

Answer:

The required equation is $f(x)=\frac{1}{x+3}-2$ .

Step-by-step explanation:

The parent function of a rational function is

$g(x)=\frac{1}{x}$

The transformation is defined by the function

$f(x)=\frac{1}{x+a}+b$

Where, a represents the horizontal shift and b represents the vertical shift.

If a>0, then graph of parent function will shift left side and if a<0, then graph of parent function will shift right side.

If b>0, then graph of parent function will shift upward and if b<0, then graph of parent function will shift downward side.

Since the graph of parent function shifts 3 units left and 2 units down. Therefore the value of a is 3 and the value of b is -2.

The new function is

$f(x)=\frac{1}{x+3}-2$

Therefore the required equation is $f(x)=\frac{1}{x+3}-2$ .

twelve cookies are cut from a rectangle of dough measuring 12 inches by 16 inches. How many square inches of dough are left over

valentina_108 [34]

Given:

Here twelve cookies are cut from a rectangle of dough measuring 12 inches by 16 inches.

Required:

How many square inches of dough are left over

the radius of cooke is 2 inches because if we cut cookie s in this formation and we get 4 cookies in horizontal so there are 4 diameter of each cookie and the total of these 4 diameter is 16.

So now the measure of one cookie is

$\frac{16}{4}=4\text{ inches}$

now the diameter of one cookie is 4 inches so by this we can find the radius

$\begin{gathered} r=\frac{d}{2} \\ r=\frac{4}{2}=2\text{ inches} \\ \end{gathered}$

now first we find the area of dough which isin rectangle shape

area of rectangle is

$A_1=12*16=192\text{ inches}^2$

now we have to find the area of 12 cookies

area of cookies is

$A_2=12*\pi *r^2=12*\pi *4=48\pi\text{ inches}^2$

now after cut dough for 12 cookies and the left over dough is

Final answer:

$A=A_1-A_2=192-48\pi\text{ inches}^2$
