Please help me i will give brainliest! it would be so helpful if you answered in complete sentences, if they are good answer I will do a 100 point giveaway after! look at the pic with the graph and description then answer the questions like this...
a.) answer
b.) answer
and so on

I tried my best, Hoped I helped. I did the first page, the other pages I’m see if I can do it.

a) How much would it cost to ship a package weighing 3.2 pounds? Explain how you arrived at your answer.

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)What type of graph is needed to represent the Media Mail shipping prices as a function of the weight of the books shipped? Explain your thinking.

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)Graph the Media Mail shipping prices as a function of the weight of the books shipped.

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)

Enjoy!

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
