Front

What is the definition of a logarithm?

Back

A logarithm is the inverse operation to exponentiation, answering the question: to what exponent must a base be raised to produce a given number.

Front

What is the base of a logarithm?

Back

The base of a logarithm is the number that is raised to a power to obtain a certain value.

Front

What is the change of base formula for logarithms?

Back

log_b(a) = \frac{log_k(a)}{log_k(b)} for any base k.

Front

What does a vertical stretch of a function do?

Back

A vertical stretch multiplies the output of the function by a factor greater than 1, making the graph taller.

Front

What does a horizontal shift of a function do?

Back

A horizontal shift moves the graph left or right along the x-axis.
