Question

Функции заданы формулами у=4х-6,у=-0,2х+5,у=8х,у=-4х+3 Какие из этих функций являются возрастающими?

Answer 1

Смотри в приложении:

Answer 2

Ответ:

1,3 - возрастает, 2,4 - убывает.

Объяснение:

Где коэффициент перед x - положительный, там возрастает, где отрицательный - убывает.

Answer 3

Functions and Their Increasing/Decreasing Nature

To determine which of the given functions are increasing, we need to analyze the slopes of the functions. A function is considered increasing if its slope is positive.

Let's examine each function and determine if it is increasing or not:

1. y = 4x - 6: - The slope of this function is 4, which is positive. Therefore, this function is increasing.

2. y = -0.2x + 5: - The slope of this function is -0.2, which is negative. Therefore, this function is decreasing.

3. y = 8x: - The slope of this function is 8, which is positive. Therefore, this function is increasing.

4. y = -4x + 3: - The slope of this function is -4, which is negative. Therefore, this function is decreasing.

In summary, the functions that are increasing are y = 4x - 6 and y = 8x. The functions that are decreasing are y = -0.2x + 5 and y = -4x + 3.
