Inverse Of The Function

[deadiam2]

I am trying to find the inverse of the function for:

f(x)=-4-x/-5-3

i know i need to substitue y in for x but beyond that i am clueless.

It's unclear what your problem is. Use some of these--------> ( )

f(x) = (-4 - x) / (-5 - 3x)

sorry about that

f(x) = (-4 - x) / (-5 - 3x)

An inverse is a reflection across x = y. Just switch their roles.

Generally, that would be:

f(x) = (-4 - x) / (-5 - 3x)
y = (-4 - x) / (-5 - 3x)
Swap x and y
x = (-4 - y) / (-5 - 3y)
{re}Solve for y

Think really hard about the Domain and Range of each expression.

Thanks for the help, I got it....
