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(x) = 19, what does this mean?

Back

This means that when the input value 'x' is substituted into the function f, the output is 19.

Front

How do you find the value of x when f(x) = 19?

Back

You need to determine which input value of x results in the output of 19 based on the function's definition.

Front

What does f(-1) represent?

Back

f(-1) represents the output of the function f when the input is -1.

Front

If f(-1) = -3, what does this indicate?

Back

This indicates that when the input to the function is -1, the output is -3.

Front

How do you evaluate f(4)?

Back

To evaluate f(4), substitute 4 into the function and calculate the output.

Front

If f(4) = 3, what does this mean?

Back

This means that when the input to the function is 4, the output is 3.

Front

What is the significance of f(3) = 4?

Back

This indicates that the function outputs 4 when the input is 3.

Front

What does f(-3) = 17 tell us?

Back

This tells us that when the input to the function is -3, the output is 17.

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.
