It appears to be asking for affirmative and negative of tú command.
Tú affirmative: same as indicative present tú (exa: comer to comes)
Tú negative: indicative tú command, change a to e, e to a(ar to er/ir ending, er/ir to ar ending)(exa: comer to no comas, acabar to no acabes)
Use the base word of subjunctive present first person(jueg of guegue)to be the base in commands to remember irregulars, because stem change along with a whole bunch of other changes apply to command and subjunctive indicative, Da!!!
