What is function notation?

Back

Function notation is a way to represent a function using symbols, typically in the form f(x), where f is the name of the function and x is the input variable.

What does the notation f(x) represent?

Back

f(x) represents the output of the function f when the input is x.

What is the value of f(x) = x^2 + 7 when x = 1?

Back

f(1) = 8.

Front

How do you evaluate a function at a given value?

Back

To evaluate a function at a given value, substitute the value into the function's equation and simplify.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (f(x) values) that the function can produce.
