Question

Найдите значение функции f(x)=2х-5 при х=-2;-1;0;1

Answer 1

F(x)=2*(-2)-5=-4-5=-9
f(x)=2*(-1)-5=-2-5=-7
f(x)=2*0-5=-5
f(x)=2*1-5=2-5=-3

Answer 2

To find the values of the function f(x) = 2x - 5 for the given values of x, simply substitute each value into the function and perform the calculations:

1. For x = -2: f(-2) = 2(-2) - 5 = -4 - 5 = -9

2. For x = -1: f(-1) = 2(-1) - 5 = -2 - 5 = -7

3. For x = 0: f(0) = 2(0) - 5 = 0 - 5 = -5

4. For x = 1: f(1) = 2(1) - 5 = 2 - 5 = -3

So, the values of the function f(x) for x = -2, -1, 0, and 1 are -9, -7, -5, and -3, respectively.
