To find the inverse, interchange the variables and solve for y.

**h ^{-1}(x)=x+1/8-3x**

Thanks Bliss,

And welcome to web2.0calc forum.

I know already that I am going to like you.

Your answer is right but you forgot the brackets. Without the brackets your answer really is not right.

x+1/8-3x = x+3x-1/8 = 4x - 0.125

this is not what you intended.

Maybe you already know this but the inverse of a function is the reflection of the graph across the line y=x

So you can always check your answer by graphing it.

Desmos is a very nice online graphing calculator.
