[{"id":31000,"question":"Quelle est la formule de la dérivée de la fonction f(x) = x² + 3x - 5 ?","option_a":"A) f'(x) = 2x + 3","option_b":"B) f'(x) = x² + 3","option_c":"C) f'(x) = 2x + 5","option_d":"D) f'(x) = 3x² + 3","option_e":"","option_f":"","bonne_reponse":"a","explication":"La dérivée de x² est 2x, celle de 3x est 3, et la dérivée d'une constante est 0. Donc f'(x) = 2x + 3.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"A) f'(x) = 2x + 3\", \"b\": \"B) f'(x) = x² + 3\", \"c\": \"C) f'(x) = 2","_debug_options_count":4},{"id":31001,"question":"La phrase 'Les élèves réussissent leur devoir' est à la voix passive.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"La phrase est à la voix active.
