Question 1100902
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 = {{{((x+2))/3}}} is the inverse
Graphically (assume that is what you mean when you say "compositing")
{{{ graph( 300, 300, -4, 4, -4, 4, 3x-2, (x+2)/3) }}}
