The reward is 20 ! confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. f(x) = ((x - 7) / (x + 3)) g(x) = - 7) / (x - 1))this is too complicated fort-t

Good use of parentheses in asking the question; fellow questioners take note.

It looks like we have some algebra ahead of us:

When we have a complicated fraction like that it's best if we multiply top and bottom by the inner denominators to simplify:

OK, now the other way.

Not so bad.

here's a poem i finished a while ago. i hope you like it and that it inspires you.
