Front

What is function notation?

Back

A way to represent a function using symbols, typically f(x), where f is the function name and x is the input.

Front

What does f(x) represent?

Back

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

Front

If f(x) = 3x + 2, what is f(0)?

Back

f(0) = 2

Front

What is the domain of a function?

Back

The set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

The set of all possible output values (f(x) values) for the function.
