Guess the function based on its plot on the left. Tick marks on axes indicate x = ±1 and y = ±1. Functions here are made of values x, 1, and 2, modified by functions ^2 (square), ^3 (cube), sin, exp, and ln, combined by operators +, -, *, /.

Enter your answer in postfix (reverse Polish) notation. For example, express 1 - x / (sin x) as "1 x x sin / -".

The correct answer will be six tokens. Numerically equivalent rearranged answers will be accepted.
