The rate of change of a function at a specific point in time.

The instantaneous rate of change of $f(x)$ with respect to $x$.

Units of $f(x)$ divided by units of $x$.

1. Find the derivative $f'(t)$. 2. Evaluate $f'(a)$. 3. Include units.

1. Find $L'(t)$. 2. Evaluate $L'(5)$. 3. Include units (likes per day).

1. Find $G'(t)$. 2. Evaluate $G'(4)$. 3. Include units (liters per minute).

The derivative represents the instantaneous rate at which a quantity is changing at a specific moment.

The instantaneous rate of change of height with respect to time (velocity).

Units provide context and meaning to the numerical value of the rate of change.
