Question

Дана функция y=f(x),где f(x)=x+7,4 при каких значениях аргумента значение аргумента f(x)=7

Answer 1

f(x)=x+7,4

f(x₁)=x₁+7.4=7

x₁=7-7,4= -0.4

ответ: -0.4

Answer 2

To find the values of the argument (x) for which the value of the function (f(x)) is equal to 7, we can set up the equation and solve for x.

Given the function f(x) = x + 7.4, we want to find the values of x for which f(x) equals 7.

Setting f(x) equal to 7:

7 = x + 7.4

Now, let's solve for x:

x = 7 - 7.4 x = -0.4

So, when x equals -0.4, the value of the function f(x) is 7:

f(-0.4) = -0.4 + 7.4 = 7
