Question 3844
this is a straight line --> it is one-to-one, so it has an inverse function.


Inverse: y=3x-4
y+4=3x
(y+4)/3 = x


The inverse function {{{f^(-1)(x) = (x+4)/3}}}


Domain and range? Well, both equations will allow any value in and can get any value out, so both functions have domain xeR and range xeR.


As for graphing them, if you are doing functions, you should be able to sketch a couple of straight lines --> look at my lessons on Linear Equations if you have trouble.
