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(x) represent in a function?

Back

f(x) represents the output of the function for a given input x. It is often equivalent to y in the equation of a function.

Front

If f(x) = 2x + 1, what is f(2)?

Back

f(2) = 2(2) + 1 = 5.

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) or y-values) that the function can produce.

How do you find f(0) for the function f(x) = -3x + 3?

Back

f(0) = -3(0) + 3 = 3.

Front

What does it mean if f(a) = b?

Back

It means that when the input to the function f is 'a', the output is 'b'.

Front

If f(x) = -2x - 8, what is f(-4)?

Back

f(-4) = -2(-4) - 8 = 8 - 8 = 0.

Front

What is the value of f(3) if f(x) = x - 2?

Back

f(3) = 3 - 2 = 1.

Front

What is the purpose of using function notation?

Back

Function notation provides a clear and concise way to express mathematical relationships and operations involving functions.
