The formula to use for the sum of n terms is as follows:
S_{n}=\frac{a(1-r^{n})}{1-r}
r = -3, n = 6.
S_{6}=\frac{4(1-(-3)^{6})}{1-(-3)}=-728

Given f(x) = the quantity of 2x minus 2 divided by 4, solve for f−1(3).
spin [16.1K]
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7

kirill115 [55]
Hello!

First you have to find the scale

32 / 4 = 8

To get the actual building you multiply the scale building by 8 and change the units to feet

8 * 8 = 64ft

The answer is 64ft

Hope this helps!
