一枚目が問題で二番目が答えなんですがわかる方教えください。

EVALUATING FUNCTIONS The symbol f(x) represents the real number in the range of the function f corresponding to the domain value x. Symbolically, f:x →S(x). The ordered pair (x, (x)) belongs to the function f. If xisa real number that is not in the domain of f, then fis not defined at x and f(x) does not exist. Examples: 15 a) Find f(6), f(a), and f(6+a) for f(x) X - 3° b) Find g(7), g(h), and g(7+h) for g(x) = 16+ 3x x. 2 c) Find k(9), 4k(a), and k(4a) for k(x) = 2 For the above functions, determine the resulting domain. Solutions: a) b) c)

NG A. Circle the causes and underline the effects in this text. ND CTS Not all reefs begin naturally. For example, an ocean current may encounter a man-made object, like a sunken ship. As a result, the water around the ship may become rich with tiny animals called plankton. A lot of small fish gather there to feed on the plankton. Consequently, larger animals are attracted to the ship. Because the ship has many little openings, many creatures also have a place to hide. In time, the ship becomes covered in polyps. As a result, it no longer looks like a ship at all.

THE SECRET TO GOOD MEMORY There is a saying in English, "In one ear and out the other." It means we hear something, and we forget it quickly. Is it true? 1 In 1895, a doctor(named Hermann Ebbinghaus)researched the question, “How quickly do people forget new information?" He found that people forget new information very quickly] Within an hour, a person forgets about 55%. Within 24 hours, a person forgets about 70%. 2 人はとれたた We do not forget all information that quickly. If you(burn, yourself on a kitchen stove, you will remember to be careful for á long time. That's because you were in danger. In the classroom, you are not in danger. In the classroom, it is easy to forget your learning. 3 How can you remember more?_You need to fepeat what you learned many timesARepetition is the secret. Language teachers say it takes at least 20 different repetitions to learn a word in a different language! This does not mean 20 repetitions in one hour. Learning requires repetition over days, weeks, and months.. 4 Why not 20 repetitions in an hour? When you repeat the same information again and again, the information stays in your short-term memory?. The information is easy to find, but it does not stay in short-term memory for long. 5 1curve: a line in a graph 2 short-term memory: the type of memory that stores information temporarily, e.g., while repeating a phone number
