Question

Функция задана формулой y=-3*x+10 При каком значении аргумента значение функции равно -2

Answer 1

Ответ:

-2=-3×x+10

-12=-3x

×=4

Ответ: Х=4

Answer 2

To find the value of the argument (x) for which the function value is equal to -2, you need to solve the equation:

y = -3x + 10

We know that the value of y (the function value) is -2. So, we can substitute -2 for y in the equation:

-2 = -3x + 10

Now, let's solve for x:

-2 - 10 = -3x

-12 = -3x

To find the value of x, divide both sides by -3:

x = -12 / -3

x = 4

So, when the argument (x) is equal to 4, the value of the function y is -2.
