Rate of change in phenomenas, experiments, observations or theories can be represented as

  • A.integral equations
  • B.differential equations
  • C.algebraic equations
  • D.logical equation

Answer: B

A rate of change is a derivative, and an equation containing derivatives is a differential equation.

\[ \frac{dy}{dt} = f(t, y) \]

This is why differential equations model so much of physics, chemistry and biology - those subjects are largely statements about how things change.
