Question about an inverse function I need to find the rule of the inverse of the function $f(x) = 6x + 4$.
Should I factorize is to $\frac{x}{6} - \frac{2}{3}$ or should I leave it as $\frac{x-4}{6}$.
Thanks 

Both are fine, but if you want to make it obvious that it is the inverse, you can put it as $\displaystyle \frac{x-4}{6}$, since it is apparent when put next to $6x+4$.
