Question

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
Graph the relationship between the number of cups and grams of flour.

Answer 4

if your graph has cups along the bottom
and grams along the side
then they gave you the points (0.5 , 64) and (2, 256)
which you can plot and draw a line through, which will make your graph :)

Answer 5

thank you and could you help me with the next small three parts?
i did the others

Answer 6

I can try :)

Answer 7

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 8

D.Evaluate g(x) for any value of x within the domain. Interpret the meaning of your solution in the context of this problem.
F.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.
G.Interpret what it means to have g(-2) and determine if this is reasonable given the situation.

Answer 9

did they give you g(x) ?

Answer 10

g(x) = 128x

Answer 11

y=128x

Answer 12

im so lost... /.\

Answer 13

me too

Answer 14

plug in any real number for x, and you'll see that it will always come out with another real number :)
in that sense, the domain should be all real numbers, right? :P

Answer 15

i supose so

Answer 16

That would be for D... but I'm not sure about F, sorry :(

G would be the idea that if you plug in a Negative number for x, you will get a negative value... but in reality can you have a negative amount of flour?

Answer 17

so for D i would put if you plug and real number in for x you will always get a real number?

Answer 18

and G i put in any negitive numbers for x, i will get a negitive value , but you cant have a negative amount of flour

Answer 19

yes :)
and for D, the meaning of x would be the amount of cups you have
and the number you get once you plug it in would be the number of grams :)

Answer 20

thank you for all your help!
