Question

Функция задана формулой f(x)=x+2/x-1 найти: f(-2)

Answer 1

$f(-2)=\frac{-2 + 2}{-2 - 1}=\frac{0}{-3}=0$

Answer 2

To find the value of the function f(x) = (x + 2) / (x - 1) at a specific point, you simply need to substitute that point's value into the function. In this case, we want to find f(-2), so we'll substitute x = -2 into the function:

f(-2) = (-2 + 2) / (-2 - 1)

Now, evaluate the expression:

f(-2) = 0 / (-3)

Division by zero is undefined, so the function f(x) is not defined at x = -2. Therefore, f(-2) is undefined.
