Question

Функцію задано формулою у = 5 - 2х. Знайдіть значення аргументу, якщо значення фукції дорівнює 7.

Answer 1

Ответ:

Объяснение:

у = 5 - 2х    y=7

7=5-2x

2x=5-7

2x=-2  | : 2

x=-1

Answer 2

Finding the Value of the Argument for a Given Function

To find the value of the argument when the value of the function is equal to 7, we can use the given function formula u = 5 - 2x. Let's solve for x.

Step 1: Substitute the value of the function (7) into the formula:

7 = 5 - 2x

Step 2: Simplify the equation:

2x = 5 - 7 2x = -2

Step 3: Solve for x by dividing both sides of the equation by 2:

x = -2/2 x = -1

Therefore, the value of the argument (x) when the value of the function (u) is equal to 7 is -1.
