Способы задания функции. Алгебра 7-11 класс.

Algebra, Grades 7-11. Today, we'll discuss methods for defining functions. This lesson will be useful for all students in grades 7-11, especially those who don't know or don't understand what methods for defining functions are and why they are needed. This lesson will help you understand how to write a function in any way and choose the most convenient method for solving exercises. First, we'll explain what a method for defining a function is and give you a hint to help you remember what it means. We'll cover eight methods for defining a function: by drawing, by arrow, by pair of numbers, by table, by formula or analytically, by description, verbally, and by symbol. For each method, we'll show where the function's components are located: the argument, the function value, the function's domain, and the function's range. The last method, "using a symbol" (F(x), S(t), Y(-2)) is the most frequently used, but isn't described in any modern textbook. We'll explain how to understand what's written and how to read these notations correctly. 00:00 Video Start. 00:50 What are the different ways to define a function? 02:54 Method 1 – with a drawing. 04:24 Method 2 – with an arrow. 06:00 Method 3 – with a pair of numbers. 07:20 Method 4 – with a table. 09:21 Method 5 – with a formula or analytically. 14:10 Method 6 – with a description. 15:59 Method 7 – verbally. 17:10 Method 8 – with a symbol.
