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.

How do you evaluate a function at a specific value?

Back

To evaluate a function at a specific value, substitute the value into the function's equation in place of the variable.

If f(x) = x + 8, what is f(-4)?

Back

f(-4) = -4 + 8 = 4.

Front

If f(x) = x - 5, what is f(8)?

Back

f(8) = 8 - 5 = 3.

Front

If f(x) = x - 5, what is f(0)?

Back

f(0) = 0 - 5 = -5.

Front

If f(x) = x - 5, what is f(-2)?

Back

f(-2) = -2 - 5 = -7.

Front

If f(x) = x - 9, what is f(4)?

Back

f(4) = 4 - 9 = -5.

Front

What does the 'x' represent in f(x)?

Back

The 'x' represents the input value or independent variable of the function.

Front

What is the output of a function?

Back

The output of a function is the result obtained after substituting the input value into the function's equation.

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that can be used in the function.
