Question

Help please how do i reword this???

Answer 1

G(5) = 128 x 5 = g(5) = 640
E. Look at the method you used to evaluate your function in part D. Explain another way you can evaluate the function for the same input.

Answer 2

Is that equation right?

Answer 3

It sames right. But what are you required to do in this question?

Answer 4

I am required to do what E tell me. Explain another way you can evaluate the function for the same input.

Answer 5

yes. That is the correct function right?

Answer 6

You evaluate it to g(5) = 640?

Answer 7

yes because 128 x 5 = 640 right?

Answer 8

Yes, but maybe the question wants you to evaluate the function to another form.

Answer 9

So i got D wrong?

Answer 10

Type the entire question here so we will know what part D is referring to.

Answer 11

2. While in the United States visiting her grandmother, Kendra copied the famous family apple pie recipe. When she returns to England, she plans on making the same apple pie for her friends. To do this, Kendra needs to convert the flour from cups to grams. She knows that 0.5 cup of flour has a mass of 64 grams and 2 cups of flour has a mass of 256 grams.
A. Write a function that shows grams as a function of cups. Use g(x). g(x) = 128x
B. Given this scenario, determine a reasonable domain for this function. A reasonable domain for this function could be 5.
C. Graph the relationship between the number of cups and grams of flour. 0<=x<infinity would be a reasonable domain. This is because there is no limit to how many people she is making the pie for.
D. Evaluate g(x) for any value of x within the domain. Interpret the meaning of your solution in the context of this problem. G(5) = 128 x 5 = g(5) = 640
E. Look at the method you used to evaluate your function in part D. Explain another way you can evaluate the function for the same input.
F. Interpret what it means to have g(-2) and determine if this is reasonable given the situation.

Answer 12

kinda big thats y i din't want to do that....

Answer 13

You guys still here?

Answer 14

Yes, I am still reading the question you give. It is really long!

Answer 15

I think that you did correctly in D.

Answer 16

Thats what i said...but luckily they only gave me three like this to do...

Answer 17

I do not know hot to make what i did in D into something else...

Answer 18

For D) they also ask you to "Interpret the meaning of your solution in the context of this problem."

g(5) = 640 means: that 5 cups of flour will weigh 640 grams.

Answer 19

Oh thanks...i would've missed that...

Answer 20

Maybe another method to evaluate the function is to write it like y=128x. Y is the number of cup; x is the number of gram.

Answer 21

So pretty much i'm leaving the equation just changed variables?

Answer 22

For E)
The problem gives you two ways to come up with a function: 1) "0.5 cup of flour has a mass of 64" or 2) "2 cups of flour has a mass of 256 grams".
A different function could be h(x) = 64/0.5 * x
Put x = 5 and you get h(5) = 64/0.5 * 5 = 64 * 10 = 640.

Answer 23

im speechless..

Answer 24

you have questions / doubts?

Answer 25

For the last part...where does g(-2) come from???

Answer 26

would you be doing g(-2) = 128 x -2?

Answer 27

Why does this chat thing mess up like that?

Answer 28

No. In the function g(x) = 128x
x is the number of cups of flour and g(x) is the weight of the flour in grams.

So x = -2 is not meaningful here. Negative 2 cups is meaningless.

Answer 29

So i would say something like this: Haveing -2 cups of flour is not reasonable in this situation because it is negative?

Answer 30

Yes. You can say x represent the number of cups and therefore a negative value for x such as -2 is not reasonable in this situation because negative number of cups is meaningless.

Answer 31

I think so. You can use 2 cups of flour to make an apple pie, but how can you make an apple pie using -2 cups of flour?

Answer 32

OK thanks!

Answer 33

You are welcome.

Answer 34

alright. yw.
