Given the function f(x) = 2x, find the value of f−1(32).

f−1(32) = 0
f−1(32) = 1
f−1(32) = 5
f−1(32) = 1

find the inverse

exchange x for y and  y for x

y=2x

then

x=2y> clear y

y=x/2

f−1(x)=x/2

for x=32

f−1(32)=32/2> 16

the answer is 16

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
