Question

Функция задана формулой f(x) =x+2÷x-1(дробь). Найти f(-2), f(3), f(-3,5)

Answer 1

для вычсления просто подставим значения х в формулу. получим то, что на рисунке

Answer 2

To find the values of the function f(x) = (x + 2) / (x - 1) at specific points, you simply need to substitute the given values of x into the formula. Let's calculate f(-2), f(3), and f(-3.5) step by step:

1. f(-2): f(-2) = (-2 + 2) / (-2 - 1) f(-2) = 0 / (-3) f(-2) = 0

2. f(3): f(3) = (3 + 2) / (3 - 1) f(3) = 5 / 2 f(3) = 2.5

3. f(-3.5): f(-3.5) = (-3.5 + 2) / (-3.5 - 1) f(-3.5) = -1.5 / (-4.5) f(-3.5) = 1/3

So, the values of the function at the given points are: f(-2) = 0 f(3) = 2.5 f(-3.5) = 1/3
