Front

What does it mean for a population to quadruple?

Back

When a population quadruples, it increases by a factor of 4. For example, if the initial population is 100, after one period of quadrupling, the population will be 400.

How do you express a population that quadruples every 8 hours mathematically?

Back

The transformations are: vertical stretch by 5, horizontal shift right by 3, and vertical shift up by 9.

Front

What is a vertical stretch in a function?

Back

A vertical stretch occurs when the output values of a function are multiplied by a factor greater than 1, making the graph taller.

Front

What is a horizontal shift in a function?

Back

A horizontal shift occurs when the input values of a function are adjusted, moving the graph left or right along the x-axis.

Front

What does a vertical shift do to a function's graph?

Back

A vertical shift moves the graph of a function up or down along the y-axis, depending on whether the constant added is positive or negative.

Front

How do you determine the growth rate in an exponential function?

Back

Front

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

Back

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