[Repro Steps]

  1. Navigate to http://www.wolframalpha.com
  2. Type y = x ^ (1/3);
  3. Hit compute button
  4. Watch the graph it produces

[Actual Result]

Only the right half of the function’s graph is produced.

I found a bug of http://www.wolframalpha.com today

 

[Expected Result]

The left half of the graph should also be produced to avoid misleading to users.
