The provided image contains a piecewise function defined as: y = { 2.5x - 1, при x < 2 11 - 3.5x, при 2 ≤ x ≤ 3 x - 2.5, при x > 3 }

Solution:

• The image displays a piecewise function.
• The function is defined in three parts based on the value of x.
• For x < 2, y = 2.5x - 1.
• For 2 ≤ x ≤ 3, y = 11 - 3.5x.
• For x > 3, y = x - 2.5.

The image defines a piecewise function:

• \[ y = \begin{cases} 2.5x - 1, & \text{if } x < 2 \\ 11 - 3.5x, & \text{if } 2 \le x \le 3 \\ x - 2.5, & \text{if } x > 3 \end{cases} \]
