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.

3.

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.
