Question

So I need help with one part of this... I will medal can somebody help? Question below

Answer 1

A.Write a function that shows grams as a function of cups. Use g(x).
B.Given this scenario, determine a reasonable domain for this function.
C.Graph the relationship between the number of cups and grams of flour.
D.Evaluate g(x) for any value of x within the domain. Interpret the meaning of your solution in the context of this problem.
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 2

PART A:
g(x) = 128x

PART B:
A reasonable domain would be x ≥ 0

PART C:

PART D:
g(5) = 128*5 = 640g

PART E:
?????

PART F:
g(-2) doesn't make a lot of sense, at least in the real world. You wouldn't need to find the weight of -2 cups. That's why it wasn't in the domain given.

Answer 3

those are my answers I have

Answer 6

@blurbendy help!!!!

Answer 7

It seems like something is missing for part A. like the question it's asking is incomplete. how can grams be a function of cups when there is nothing to evaluate?

Answer 8

Wait not the whole question is posted one second

Answer 9

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).
B.Given this scenario, determine a reasonable domain for this function.
C.Graph the relationship between the number of cups and grams of flour.
D.Evaluate g(x) for any value of x within the domain. Interpret the meaning of your solution in the context of this problem.
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 10

ok, so if .5 cup of flour = 64 grams, what do you think 1 cup of flower is?

Answer 11

oh wait, you already answered

Answer 12

you're right for A

Answer 13

\(\huge\it just~E~please\)

Answer 14

Answer 15

For E, you can just use a graph. go to some point on the x-axis, and see where it lines up on the y-axis

Answer 16

In D, you just substituted a number, (x) value, and got g(x), which is just y. another way of doing that would be to use a graph. make sense?

Answer 17

Oh yes ok!

Answer 18

cool =)

Answer 19

Oh cool.

Answer 27

Awwwww.... that is very sweet of you @blurbendy .

Answer 28

Answer 29

Yes..

We have g(x) = 128x

g(-2) means to substitute -2 for 'x':

g(x) = 128(-2)
