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.

Front

If f(2) = 4, how can this be represented as an ordered pair?

Back

(2, 4)

Front

What does f(2) = 4 imply about the function f?

Back

It means that when the input is 2, the output of the function f is 4.

Front

How do you find the value of a function at a specific point?

Back

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

Front

If f(3) = 4, what does this tell us about the function at x = 3?

Back

It indicates that the output of the function f when the input is 3 is 4.

Front

What is the output of the function f if f(1) = 1?

Back

The output is 1 when the input is 1.

Front

If f(-1) = -3, what can we say about the function at x = -1?

Back

The function outputs -3 when the input is -1.

Front

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

Back

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

Front

How can you express the relationship between inputs and outputs in a function?

Back

The relationship can be expressed as ordered pairs (x, f(x)).

Front

What does it mean if a function is defined for a certain input?

Back

It means that there is a corresponding output value for that input in the function.
