Analyze the mathematical expressions and conditions provided in the image.

Mathematical Expressions and Conditions:

• Function 1:
  y = { 2.5x - 1, при x < 2
11 - 3.5x, при 2 <= x <= 3
x - 2.5, при x > 3
• Function 2:
  y = { x + 1, при x < 0
-x^2 + 2x + 3, при x >= 0

Analysis of the OCR:

• The OCR correctly identifies the mathematical notation for piecewise functions.
• The Russian word 'при' translates to 'if' or 'when', indicating the condition under which each part of the function is applied.
• The inequalities (<, <=, >=, >) correctly define the domain for each piece of the functions.
• The use of commas as decimal separators in '2,5x' and '11 - 3,5x' is common in some locales but could be interpreted as multiplication or separate numbers in others. Assuming standard mathematical notation, these are likely intended as '2.5x' and '3.5x'.
• The second function appears to be a quadratic equation for the second piece.
