4. Call that polynomial P (x) = ax³ + bx² + cx + d

We have P(1)=a+b+c+d=3 (1)

P(2)=8a+4b+2c+d=3 (2)

P(3)=27a+9b+3c+d =7 (3)

P(4)=64a+16b+4c+d =21 (4)

From (1) and (2) => 7a+3b+c=0

From (1) and (4) => 63a+15b+3c=18

=> 12b+6c=-18 => 2b+c=-3

From (1) and (3) =>26a+8b+2c=4=> 13a+4b+c=2

=> 13a+2b=5

EX: Read the passage, and choose the correct answer A, B, C or D for each question.

For many of us, food isn't that important. However, for a few people, food is very improtant. For these people, meals are a kind of art.

These people are interested in something called "haute cuisine" . Haute cuisine is French for "high cooking" . You can usually find haute cuisine in fancy French hotels anh high level restaurants.

Haute cuisine has changed over the years, but the most important parst have remained the same. Haute cuisine meals are almost always very complicated, and they take a very long time to make. Usually, an haute cuisine meal has very many small dishes, instead of a few large ones. Also, with haute cuisine dishes, the appearance is very important. Of course, an haute cuisine dish must taste wonderful, but that is not enough. An haute cuisine dish must also look beautiful. Another very important part of haute cuisine is wine. Chefs and customers always try to select a wine that is a perfect match for their meal. The wine that people drink with haute cuisine is often very rare. You will not be surprised to hear that haute cuisine dishes are almost always very expensive.

Haute cuisine is traditionally French, but other countries have similar concepts of food. People often compare Japanese kaiseki to haute cuisine. Kaiseki is another very complicated, very high level kind of food. In Japan, kaiseki is also considered a kind of art. When Japanese chefs prepare kaiseki, they don't just consider the taste of the food. They also consider the food's texture, colour, and appearance. Chefs even match the colour of the food to the colour of the plate and the chopsticks. Of course, although haute cuisine and kaiseki share many similarities, the food itself is quite different.

If you ever get the chance to try kaiseki or haute cuisine , remember one thing: You are not just having a meal, you are enjoying a very special kind of art.
