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 value.

What does f(1) represent?

Back

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

Front

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

Back

f(1) = 2(1) + 1 = 3.

Front

If f(x) = 2x + 1, what is f(4)?

Back

f(4) = 2(4) + 1 = 9.

Front

What is the output of f(2) if f(x) = 2x + 1?

Back

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

Front

What does f(x) equal when x = 0 in f(x) = 2x + 1?

Back

f(0) = 2(0) + 1 = 1.

Front

What is the relationship between f(x) and y?

Back

f(x) is often used interchangeably with y, representing the output of the function for a given input x.

Front

If f(x) = x^2, what is f(3)?

Back

f(3) = 3^2 = 9.

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.
