Is yahoo answers shutting down forever ?

Yes as of May 4,2021 Yahoo Answers will be Closing Down for Good Its True

You can Read the Announcement from Yahoo herehttps://help.yahoo.com/kb/SLN35642.htmlHowever Yahoo Answers wont take any New Questions or Answers as of April 20 so Before the Official ShutDown they will Stop taking new Questions or Answers

The answer is yes. Declining usage and poor maintenance of the site are the mitigating factors behind Verizon's decision to shut down Answers on May 4. Two weeks before its closure (on the 20th), the site will revert to a read-only mode. That means no more Q&As will be posted after the cutoff point.

For the umpteenth time: Because Verizon Media is choosing to shut it down (just as they did Yahoo Messenger and Yahoo Groups). No specific explanation was given, but considering the significant decline in quality of content on the site versus the cost of cleaning it up and keeping it running, it's not a surprise (a disappointment, but not a surprise). Do you really think this question hasn’t been asked dozens of times already? One need only review the question list to find the responses.

Yes.  As for why, it's a corporate decision.
