FLASHCARD QUESTION
Front
What does the base of an exponential function represent?
Back
The base of an exponential function indicates the growth (if greater than 1) or decay (if between 0 and 1) rate of the function.
3.
FLASHCARD QUESTION
Front
How do you determine the growth rate from an exponential function?
Back
The growth rate can be determined by subtracting 1 from the base of the function. For example, in f(x) = a(1 + r)^x, r is the growth rate.

What is the decay rate in the function f(x) = 800(0.85)^x?
Back
The decay rate is 15%, which is calculated as 1 - 0.85.

FLASHCARD QUESTION
Front
How do you write an exponential function for a situation involving growth?
Back
To write an exponential function for growth, use the formula C(t) = C_0(1 + r)^t, where C_0 is the initial amount, r is the growth rate, and t is time.

FLASHCARD QUESTION
Front
What is the formula to calculate the future value of an investment with exponential growth?
Back
The future value can be calculated using the formula A = P(1 + r)^t, where A is the amount of money accumulated after n years, P is the principal amount, r is the annual interest rate, and t is the number of years.
