What is exponential growth?

Back

Exponential growth occurs when the increase in a quantity is proportional to its current value, leading to growth at a constant rate over time. For example, a population that doubles in size at regular intervals.

Define half-life in the context of radioactive decay.

Back

Half-life is the time required for half of the radioactive atoms in a sample to decay. It is a constant for each radioactive isotope.

How much of a substance remains after 3 half-lives?

Back

After 3 half-lives, 1/8 of the original amount remains, as each half-life reduces the quantity by half.

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

Back

The base in an exponential function indicates the growth or decay factor. A base greater than 1 indicates growth, while a base between 0 and 1 indicates decay.
