Question

Молю: какие из точек а(3 -2) в(-2 4) с(1 2) D(-3 1) принадлежат графику функции у=2х+4"

Answer 1

А(3 -2)
х=3  у=-2
Подставим х и у в выражение , которым задана функция
у=2х+4
-2=2·3+4
-2=10 - неверно.
Точка А не принадлежит графикуфункции у=2х+4

 В(-2 4)
х=-2 у=4
4=2·(-2)+4
4=0  - неверно
Точка В не принадлежит графикуфункции у=2х+4

С(1 2)
х=1 у=2
2=2·1+4
2=6 - неверно
Точка С не принадлежит графикуфункции у=2х+4

D(-3 1)
х=-3 у=1
1=2·(-3)+4
1=-2 - неверно
Точка Д не принадлежит графику функции у=2х+4

Answer 2

I can understand and communicate fluently in your language of choice. I see that you are asking a math question. To check if a point belongs to the graph of a function, you need to substitute the x and y coordinates of the point into the function and see if the equation is true. For example, to check if the point A(3, -2) belongs to the graph of the function y = 2x + 4, you need to plug in x = 3 and y = -2 into the function and see if -2 = 2 * 3 + 4. This is not true, so the point A does not belong to the graph. You can use the same method to check the other points. Here is a table that shows the results:

| Point | Equation | Belongs to the graph | | --- | --- | --- | | A(3, -2) | -2 = 2 * 3 + 4 | No | | B(-2, 4) | 4 = 2 * (-2) + 4 | No | | C(1, 2) | 2 = 2 * 1 + 4 | No | | D(-3, 1) | 1 = 2 * (-3) + 4 | Yes |

As you can see, only the point D belongs to the graph of the function y = 2x + 4. I hope this helps you understand the problem better. If you have any other questions, feel free to ask me.Ответь+подробно.+Молю:+какие+из+точек+а(3+-2)+в(-2+4)+с(1+2)+D(-3+1)+принадлежат+графику+функции+у=2х+4
