of events or trials in a probability experiment.
A number that indicates how many times a number or
expression is to be multiplied by itself. Example: In the
expression 53, the exponent is 3.
Exponential decay occurs when a quantity decreases
exponentially over time.
A function that can be described by an equation of the form y =
ax, where a > 0 and a ≠ 1.
Exponential growth occurs when a quantity increases
exponentially over time.
