Question

У=2х-4 Значения аргумента при котором функция принимает положительное значение

Answer 1

У=2х-4

2х-4>0

2x>4

x>2       x∈(2;+∞)

Answer 2

To find the values of the argument (x) for which the function takes a positive value, we need to set the function equal to a positive number and solve for x. In this case, we want to find the values of x when the function (U) is positive.

The function is given by U = 2x - 4.

Let's set U greater than zero and solve for x:

2x - 4 > 0

Now, let's isolate x:

2x > 4

Next, divide both sides by 2:

x > 2

So the values of x for which the function U = 2x - 4 takes a positive value are all x values greater than 2. In interval notation, this can be written as: (2, +∞). This means any value of x greater than 2 will result in a positive value for the function.
