The gerund is the verb form ending in -ing. It functions as a noun in the following cases:

As a direct object of some verbs: avoid, consider, deny, detest, dislike, enjoy, finish, miss, recommend, suggest, etc. Many people recommend using the Uber app.
After prepositions. Mia isn’t keen on going to hotels. She prefers renting flats.
After some structures: be used to / get used to, can’t help, can’t stand, don’t mind / wouldn’t mind, feel like, it’s no use, look forward to, see myself, etc. I wouldn’t mind trying out this restaurant.
As the subject of the sentence when talking about actions or facts in general. Smoking is bad for your health.

The infinitive is the verb form preceded by ‘to’ and is used in these cases:

After verbs like afford, agree, appear, choose, decide, expect, hope, learn, offer, plan, promise, refuse, seem, want, wish, etc. She can’t afford to buy that coat.
After some adjectives and adverbs. She got up early to take the bus.
After the indirect object of verbs like advise, help, invite, persuade, teach, tell, warn, etc. My friend warned me not to live beyond my means.

However, make and let are followed by an indirect object + the base form (infinitive without ‘to’). My parents let me do odd jobs.
