Function Notation

Front

What is function notation?

Back

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

What does f(2) = 5 mean?

Back

It means that when the input value is 2, the output of the function f is 5.

Front

How do you find f(3) if f(3) = 4?

Back

You substitute 3 into the function and find that the output is 4.

Front

What is the output of f(-3) if f(-3) = 17?

Back

The output of the function when the input is -3 is 17.

Front

If f(x) = 19, what is the value of x when f(x) = 19?

Back

The value of x is 3.

Front

What does it mean if f(x) is defined for all real numbers?

Back

It means that the function can take any real number as an input.

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.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function at a specific point, substitute the input value into the function's equation.

Front

What is the significance of the notation f(x)?

Back

The notation f(x) indicates that f is a function of x, meaning that the output depends on the input x.
