Activator and repressor bind DNA. Activator = transcription; repressor = no transcription (simplified).
Inducer does NOT bind DNA. Inducer binds either activator OR repressor. It makes activator BETTER able to bind DNA = more transcription OR it makes repressor LESS able to bind DNA = transcription.
