Знаменатель дроби не может быть равен 0, поэтому х-9≠0 и поэтому х≠9. В остальных точках функция имеет значения.d(f) = (-∞; 9) U (9; +∞)

TEXT 14
THEATRE

The theatre has recently become less popular than the cinema and lost even more of its attraction due to the popularity of television and since the appearance of video and DVD. Besides, theatre tickets are very expensive, especially in good theatres. So we can say that a visit to a famous theatre has become a luxury.
Still, the theatre is an inseparable part of the cultural life of any country. We can even say that the theatre as an art reflects the state of society and of the mind of the nation. In every country theatre has its own history, traditions, and peculiarities.
Theatre was one of the most important branches of art in Ancient Greece. Ancient Greek plays have some peculiarities due to the strict rules the Greeks had for theatre, but they are still very popular and we can say that the Ancient Greece is the birthplace of the theatre. In medieval times the theatrical art was often disapproved by the church, but at the same time there were things like sacred plays representing in dramatic form the Bible stories. Since 16th century theatre has become one of the most popular forms of entertainment.
There are a lot of theatres in Russia and some of them are popular all over the world. In Moscow theatre-goers try not to miss the first nights at the Vakhtangov, Sovremennik, or Khudozhestvenny (Art) theatres. St. Petersburg also has a variety of theatres, which meet all the tastes. Lovers of classic music never miss a chance to visit, the Philharmonic Society Hall. Opera and ballet lovers can go to Mariinsky opera house and Maly opera house. Those who are fond of drama visit the Bolshoi Drama Theatre, Alexandrinsky Theatre, Lensovet theatre, and many others. Many new theatres and studios have appeared during the last five or ten years. Many theatres are famous for their excellent company, sets, and great directors.
