Answer: Derivatives of a function.
- A Algebraic variables without any calculus operations
- B Derivatives of a function
- C Integral expressions rather than derivative ones
- D Constant terms with no variable component
Correct answer: B. Derivatives of a function
Explanation: A differential equation contains derivatives (dy/dx, d²y/dx², etc.) of one or more functions.
The general solution y=Ax² represents an entire FAMILY of curves, one for each value of the arbitrary constant A; a particular solution (fixed by an initial condition) selects exactly one curve from this family.
