Replace f(x) with y:
y = 3x +2
interchange the variables:
x = 3y +2
switch the equation so the Y is on the left side:
3y +2 = x
subtract 2 from each side:
3y = x-2
divide each term by 3 to get y alone:
y = (x-2)/3
replace y with inverse of F(x) which is f^-1(x):
f^-1(x) = -(x-2)/3

Answer:
10 feet
Step-by-step explanation:
Salvador has a rug in his bedroom with perimeter of 36 feet, the length of the rug is 8 feet what is the width of the rug?
The rug is shaped as a rectangle
The formula for the Perimeter of a rectangle = 2L + 2W
Perimeter = 36 feet
Length = 8 feet
Hence
36 = 2(8) + 2W
36 = 16 + 2W
2W = 36 - 16
2W = 20
W = 20/2
W = 10 feet
Therefore, the Width of the rug is 10 feet
