Front

What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

What does f(x) represent in a function?

Back

f(x) represents the output of the function f for a given input x.

Front

If f(x) = 25, what values of x satisfy this equation?

Back

x can be 8 or 16.

Front

How do you find f(6) if f(x) is defined?

Back

Substitute 6 for x in the function definition and calculate the output.

Front

What is the independent variable in a function?

Back

The independent variable is the input variable, commonly represented as x.

Front

What is the dependent variable in a function?

Back

The dependent variable is the output variable, commonly represented as f(x) or y.

Front

If f(x) = 4, what is the value of x?

Back

x is 2.

Front

What is the purpose of evaluating a function?

Back

Evaluating a function allows us to find the output for a specific input.

Front

What does it mean to solve for x in a function?

Back

To solve for x means to find the input value(s) that make the function equal to a specific output.

Front

What is the notation for a function?

Back

Functions are typically written in the form f(x), where f is the function name and x is the input.
