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
How do you solve an exponential equation?
Back
To solve an exponential equation, you typically rewrite both sides of the equation with the same base, then set the exponents equal to each other.

FLASHCARD QUESTION
Front
What is the base of an exponential function?
Back
The base of an exponential function is the constant 'b' in the function f(x) = a * b^x, which determines the growth or decay rate.
4.
FLASHCARD QUESTION
Front
What does it mean for a function to exhibit exponential growth?
Back
Exponential growth occurs when the base 'b' in the function f(x) = a * b^x is greater than 1, resulting in the function increasing rapidly as 'x' increases.
5.
FLASHCARD QUESTION
Front
What does it mean for a function to exhibit exponential decay?
Back
Exponential decay occurs when the base 'b' in the function f(x) = a * b^x is between 0 and 1, resulting in the function decreasing rapidly as 'x' increases.

FLASHCARD QUESTION
Front
How can you express 8 as a power of 2?
Back
8 can be expressed as 2^3, since 2 * 2 * 2 = 8.
7.
FLASHCARD QUESTION
Front
What is the first step in solving the equation 8 = 2^(5x + 7)?
Back
The first step is to rewrite 8 as 2^3, allowing you to set the exponents equal: 3 = 5x + 7.
