Question

Am I right?



Greg made pudding every weekend. The more times he made pudding, the more practice he gained. The time he took to make the same amount of pudding every week decreased with practice. The function below shows the number of hours f(x) Greg took to make pudding after he had made it x times.

(x) = 2(0.8)x

Which graph best represents the function?

Answer 1

I think its graph B.

Answer 2

@sidsiddhartha

Answer 3

what school is this with

Answer 4

it look's right

Answer 5

Lol, FLVS.

Answer 6

its \[<x>=2(0.8)x~~or\\<x>=2(0.8)^x\]

Answer 7

?
So, am I right or....

Answer 8

ok taking
\[f<x>=2(0.8)^x\]
so
f(1)=1.6
f(2)=1.28
f(3)=1.024
f(4)=0.8192
so f(x) decreases as x increase

Answer 9

so its the last one

Answer 10

Oh! I get it now. I can't believe I missed that. Thank you!

Answer 11

starting from 2 because at x=0 f(x)=2
