FLASHCARD QUESTION

Front

What is an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a(1 + r)^x, where 'a' is the initial amount, 'r' is the rate of growth (as a decimal), and 'x' is the time period.

FLASHCARD QUESTION

Front

What does it mean for a function to be linear?

Back

A linear function is a function that adds the same value each time, represented by the equation f(x) = mx + b, where 'm' is the slope and 'b' is the y-intercept.

FLASHCARD QUESTION

Front

How do you calculate the future value of an investment using exponential growth?

Back

Future Value = Present Value * (1 + r)^t, where 'r' is the growth rate and 't' is the number of time periods.

FLASHCARD QUESTION

Front

What is the difference between linear and exponential growth?

Back

Linear growth adds a constant amount over time, while exponential growth multiplies by a constant factor, leading to faster increases as time progresses.

If a car is worth $29,000 and increases by 10% each year, what will it be worth in 5 years?

Back

$46,704.79

FLASHCARD QUESTION

Front

What is the formula for exponential decay?

Back

Exponential decay can be represented as f(x) = a(1 - r)^x, where 'a' is the initial amount and 'r' is the decay rate.

7.

FLASHCARD QUESTION

Front

What is the formula for compound interest?

Back

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 number of years.
