What would the value of 0 represent in her data?

My family hates me

Step-by-step explanation:

a) 

Shipping cost of 3.2 package is $4.13.

We can't use the cost assigned to 3

lbs because the package is over 3 lbs but it is not over 4 lbs so we use the

cost of 4lbs. (check the attachment for price)

b)

Line graph is needed to represent

the Media Mail shipping prices as a function of the weight of the books

shipped.

In line graph, x values represent the

weight in pounds and the y values represent the cost.

c) Answer;

When we graph the Media Mail shipping

prices as a function of the weight of the books shipped, it will be;

f(x) = 2.69 + 0.48(x-1)

d)

domain

is the x values; range is the y values

We can

define the domain of a function

f(x) as the set of all values for which the function is defined, and the range of the

function refers to the set of all values that f takes.

e)

Given that;

x =

number of books purchased

f(x) =

price of shipping one order of books

fixed

fee = 3 per order

variable

fee: 1.99 per book

thus

the function will be;

f(x) =

3 + 1.99x

Assuming

the x =

f(0) =

3 + 1.99(0)

f(0) =

3 + 0

f(0) = 3

f)

check the attachment. Graph part 1 f

g) The graph is

continuous because the x-values can have any input as a point.

That graph is a continuous, means it is like

unbroken line. Therefore we want to say that f(x) is a continuous function. But

a function is a relationship between numbers. 

Part 2;

Area =

8,100 square feet

area of

a square = a²

8,100

square feet = a²

√8,100

square feet = √a²

90 feet

= a

total

length each row of bookshelf is 4/5 of the length of the storage space.

90 feet

* 4/5 = (90*4)/5 = 360/5 = 72 feet.

Area =

(72 ft)²

Area =

5,184 square feet.

Part 4:

a)

let x represent the amount of a transaction

and f(x) represent the amount Isabel is charged for the transaction

then;

f(x) = 1.5(x)

c) The domain and range are both negative infinity to positive infinity.

We can define the domain of a function f(x) as the set of all values for which the function is defined, and the range of the function refers to the set of all values that f takes

rick would give her the best deal as he will charge $8.88 per hour
