What is Exponential Growth?

Back

Exponential Growth occurs when a quantity increases by a consistent percentage over a period of time, resulting in a rapid increase.

Front

What is Exponential Decay?

Back

Exponential Decay occurs when a quantity decreases by a consistent percentage over time, leading to a rapid decrease.

Front

What is a Logarithmic Function?

Back

A Logarithmic Function is the inverse of an exponential function, representing the power to which a number must be raised to obtain another number.

Front

How do you identify the initial value in an exponential equation?

Back

The initial value is the coefficient of the exponential term when the equation is in the form y = a(b)^x.

Front

What is the general form of an exponential decay equation?

Back

The general form is y = a(1 - r)^x, where 'a' is the initial amount and 'r' is the decay rate.

Front

What is the formula for exponential growth?

Back

The formula for exponential growth is y = a(1 + r)^x, where 'a' is the initial amount and 'r' is the growth rate.

Front

How do you add polynomials?

Back

To add polynomials, combine like terms by adding their coefficients.

Front

What is the initial value in the equation y = 6.87(4)^x?

Back

The initial value is 6.87.

Front

What does the term 'depreciation' mean in finance?

Back

Depreciation refers to the reduction in the value of an asset over time, often due to wear and tear.

Front

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

Back

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