inverse equation of f(x)=3x+4 please show all steps

Question

jim_thompson5910 · Answer

The idea is to replace f(x), swap x and y, then solve for y.

f(x)=3x+4

y=3x+4

x=3y+4

x-4=3y

(x-4)/3 = y

y = (x-4)/3

So the inverse function is $$\Large f^{-1}(x) = \frac{x-4}{3}$$

oops meant to write "replace f(x) with y"
