What is exponential decay?

Back

Exponential decay refers to a process where a quantity decreases at a rate proportional to its current value. An example is the depreciation of a car's value over time.

Which scenario represents exponential decay?

Back

Mrs. Evans buys a new car. Every year that passes by, the value decreases by 10%.

Front

What is exponential growth?

Back

Exponential growth occurs when a quantity increases at a rate proportional to its current value. An example is bacteria that double in amount every day.

Front

What does the graph of an exponential function look like?

Back

The graph of an exponential function rises or falls sharply, depending on whether it represents growth or decay, and approaches the x-axis but never touches it.

Front

What is the base of an exponential function?

Back

The base of an exponential function is the constant that is raised to a variable exponent, determining the rate of growth or decay.
