Question

Функция задана формулой 2x+7 при каком значении аргумента значение функции равно 5

Answer 1

При x равном минус один

Answer 2

To find the value of the argument (x) for which the function's value is equal to 5, you need to set the function equal to 5 and solve for x.

Given function: f(x) = 2x + 7

Set f(x) equal to 5:

2x + 7 = 5

Now, we need to isolate x on one side of the equation. First, subtract 7 from both sides:

2x = 5 - 7 2x = -2

Next, divide both sides by 2 to solve for x:

x = -2 / 2 x = -1

So, when the argument (x) is equal to -1, the value of the function is 5.
