Question

Need some help :3

Answer 1

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.

-Write a function that shows grams as a function of cups. Use g(x).
-Given this scenario, determine a reasonable domain for this function.
-Graph the relationship between the number of cups and grams of flour.
-Evaluate g(x) for any value of x within the domain. Interpret the meaning of -your solution in the context of this problem.
-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.
-Interpret what it means to have g(-2) and determine if this is reasonable given the situation.

Answer 5

i would say that the function is like this
g(x)=128x
where he have 128 gram per a cup
since we have 1/2 is 64 grams
you would go to say that 1 cup gives 128 grams

Answer 6

where we have*

Answer 7

ok, so what about the rest of the parts?

Answer 8

a reasonable domain i would say where the function doesn't give negative inputs
which wouldn't make sense in this real situation

Answer 9

can you determine that?

Answer 10

i meant output not input my bad^_^

Answer 11

i will give you and example g(-1)=-128 grams
does this make sense in this real life situation

Answer 12

I dont know

Answer 13

well it's obvious that we don't deal that way in real life situation
like i need -128 grams to make a pie?

Answer 14

well, thats not possible

Answer 15

let's say we start with 0 cups of flour that would make 0 grams of flour
which make sense in our real life situation
that translated as no flour

Answer 16

So we can say that the domain in this case would be from 0 up

Answer 17

Im really sorry, but i only have 5 minutes. can you plees be a little faster?

Answer 18

I can graph it

Answer 19

yeah pretty easy. a line that starts from 0 and goes up

Answer 20

evaluate g(x)! just choose whatever number for x and evaluate it

Answer 21

on to [part D:

Answer 22

that one is for part D

Answer 23

another way to find output for the same input is graphically

Answer 24

choose an easy value so you will get and easy output

Answer 25

the last one! we already said it is not reasonable to have -1 cups
-2 cup ant etc...
in general, having negative values for output in this real life case is not withing our reason haha
however in world of mathematics that has perfect sense

Answer 26

pls think about the rest and see it through^_^

Answer 27

ty!

Answer 28

anytime!
