What is Exponential Decay?

Back

Exponential decay is a decrease in a quantity that follows an exponential function, where the rate of decrease is proportional to the current value. For example, if a population decreases by a certain percentage each year, it is experiencing exponential decay.

Front

What is the common ratio in exponential decay?

Back

The common ratio in exponential decay is calculated as 1 minus the decay rate. For example, if the decay rate is 12%, the common ratio is 1 - 0.12 = 0.88.

What does a starting point of a function represent?

Front

How do you identify if data is Discrete or Continuous?

Back

Discrete data consists of distinct, separate values, often counted in whole numbers (e.g., number of frogs). Continuous data can take any value within a range (e.g., height, weight).

What is the formula for exponential decay?

Back

Front

What is a decay rate?

Back

The decay rate is the percentage at which a quantity decreases over a specific period. For example, a decay rate of 12% means the quantity decreases by 12% each time period.

Front

What is the significance of the base in an exponential function?

Back

The base in an exponential function determines the rate of growth or decay. A base less than 1 indicates decay, while a base greater than 1 indicates growth.

Front

How do you calculate the amount remaining after exponential decay?

Back

Front

What is the difference between linear and exponential functions?

Back

Linear functions have a constant rate of change, represented by a straight line, while exponential functions have a variable rate of change, represented by a curve that increases or decreases rapidly.

Front

What is a graph of exponential decay?

Back

A graph of exponential decay shows a curve that starts at a certain value and decreases towards zero, never actually reaching it. It slopes downward as time increases.
