True. 'Look after' is a common phrasal verb that means to be responsible for or to care for someone or something. Example: 'Parents look after their children by providing food and shelter.' It's different from 'look for', which means to search, or 'look at', which means to observe. Phrasal verbs can be separable or inseparable, but 'look after' is inseparable, meaning the object always comes after the particle.
