hi, I need help finding the inverse of this problem:
f(x)=1-3x
I usually dont have trouble but what ever answer i get when I try to check it, it doesnt work. please help.

It's pretty much the same as y=1-3x, where y is the range and x is the domain. Now switch x and y, to get x=1-3y, and solve for y.
You should get:
x=1-3y
x-1=-3y
y=-1/3x+1/3

Is this what you need?
x = (1-f(x))/3

Isnt it supposed to be f(y) =1-3x ?
inverse is (1-x)/3

f(x)=1-3x
inverse is f(x)= (1+x)/3
