FLASHCARD QUESTION

Front

What is an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a * b^x, where 'a' is a constant, 'b' is the base (a positive real number), and 'x' is the exponent.

FLASHCARD QUESTION

Front

What does it mean for a function to exhibit exponential growth?

Back

Exponential growth occurs when a quantity increases by a constant percentage over equal time intervals, resulting in a rapid increase.

FLASHCARD QUESTION

Front

What does it mean for a function to exhibit exponential decay?

Back

Exponential decay occurs when a quantity decreases by a constant percentage over equal time intervals, resulting in a rapid decrease.

FLASHCARD QUESTION

Front

How do you calculate compound interest?

Back

The formula for compound interest is A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, P is the principal amount, r is the annual interest rate, n is the number of times that interest is compounded per year, and t is the time in years.

FLASHCARD QUESTION

Front

What is the initial value in an exponential function?

Back

The initial value is the value of the function when x = 0, represented by 'a' in the function f(x) = a * b^x.

FLASHCARD QUESTION

Front

How do you identify exponential growth from an equation?

Back

Exponential growth can be identified if the base 'b' in the function f(x) = a * b^x is greater than 1.

FLASHCARD QUESTION

Front

How do you identify exponential decay from an equation?

Back

Exponential decay can be identified if the base 'b' in the function f(x) = a * b^x is between 0 and 1.
