The order of the differential equation of family of parabolas whose axes are parallel to y-axis is 

A parabola is a U-shaped curve that is the graph of a quadratic function. It can open upward or downward depending on the sign of the leading coefficient. Parabolas are symmetric, with a vertex as the highest or lowest point. They have applications in physics, engineering, and geometry.

Class 12 Maths Chapter 9 on Differential Equations focuses on the relationship between a function and its derivatives. It covers methods for solving first order and higher-order differential equations. The chapter includes real-life applications like population growth and motion. This topic is important for CBSE Exam 2024-25 and its practical uses.
