For the function f(x)=3x-2 Find the inverse function f^1(x).
Show that f(x) and f^1(x) are inverse functions by compositing ( in both directions)
:
y = 3x -2
swap x and y and solve for y
3y - 2 = x
3y = x + 2
y = %28%28x%2B2%29%29%2F3 is the inverse
Graphically (assume that is what you mean when you say "compositing")
+graph%28+300%2C+300%2C+-4%2C+4%2C+-4%2C+4%2C+3x-2%2C+%28x%2B2%29%2F3%29+
