V=(1/3)hpir^2
d/2=r
2.75/2=1.375
to make volume 4 times more
multiply height by 4 or multiply radius by 2
example
find current cup volume
V=(1/3)2.75pi1.375^2=2.2057291666666pi

if we times height by 4
3.5*4=14
V=(1/3)14pi1.375^2=8.822916666666666666pi

if we times radius by 2
1.375*2=5.5
V=(1/3)3.5pi5.5^2=8.822916666666666666pi


we can show it is 4 times by
8.822916666666666666pi/2.2057291666666pi= 3.99999 close enough
dimentions are

diameter of 2.75in and height of 11in or
 diameter of 5.5in and height of 3.5 in

If f(x + 1) = x + 2 then f(x - 1) is
erastova [34]

Answer: \Large\boxed{f(x-1)=x}

Step-by-step explanation:

<u>Given function</u>

f(x + 1) = x + 2

<u>Isolate [ x + 1 ] on the right-hand side</u>

f(x + 1) = x + 1 + 1

f(x + 1) = (x + 1) + 1

<u />

<u>Substitute [ x + 1 ] with x</u>

f(x) = x + 1

<u>Substitute [ x ] with [ x - 1 ]</u>

f(x - 1) = (x - 1) + 1

\Large\boxed{f(x-1)=x}

Hope this helps!! :)
