What is function notation?

Back

Function notation is a way to represent a function using symbols. It typically uses the letter 'f' followed by parentheses containing the input variable, such as f(x).

What does f(x) represent in function notation?

Back

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

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 and simplify.

If f(x) = x + 7, what is f(1)?

Back

f(1) = 1 + 7 = 8.

Front

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

Back

f(8) = 8 - 5 = 3.

Front

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

Back

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

Front

If f(x) = x - 9, what is f(-1)?

Back

f(-1) = -1 - 9 = -10.

Front

If f(x) = x - 2, what is f(4)?

Back

f(4) = 4 - 2 = 2.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x) 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)) that the function can produce.
