Question

(оценить) 2-x если -1<x<3

Answer 1

Y=2x (-1;3)

x -1 0 1 2 3
y -2 0 2 4 6

Answer 2

To evaluate the expression 2 - x when -1 < x < 3, you simply need to substitute different values of x within the given range and calculate the result.

Let's try a few values of x:

1. When x = -1: 2 - (-1) = 2 + 1 = 3

2. When x = 0: 2 - 0 = 2

3. When x = 2: 2 - 2 = 0

As the range for x is -1 < x < 3, the results we calculated fall within this range. So, the function 2 - x is defined for all values of x in the range -1 < x < 3.

To summarize:

• When x = -1, the value of 2 - x is 3.
• When x is any value between -1 and 3 (exclusive), the value of 2 - x lies within the range 0 to 3.
