Question

Which equation represents the inverse, f^-1(x), of the function f(x)=3x+1?

Answer 1

solve for \(y\) : \(x=3y+1\)

Answer 2

or else reason this way
\(f\) says
a) multiply by 3
b) add 1

inverse will say
1) subtract 1
2) divide by 3

Answer 3

To find the inverse, first switch x and y:
x=3y+1
Then solve for y, subtract 1
x-1=3y
divide by 3
(x-1)/3=y
