Let f(x)=x/x-3. Find a function y = g(x) so that f(g(x))= x
Added by Melvin J.
Step 1
In other words, we want to find g(x) such that: f(g(x)) = x We know that f(x) = x / (x - 3), so we can write: f(g(x)) = g(x) / (g(x) - 3) = x Now, we want to solve for g(x). To do this, let's multiply both sides of the equation by (g(x) - 3): g(x) = x(g(x) - Show more…
