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.

Convert g(15) = -1 to a coordinate point.

Back

(15, -1)

Front

Evaluate f(x) = 20 - 1.5x at x = 6.

Back

f(6) = 11

Front

In the expression f(2) = 5, what does 2 represent?

Back

2 is the input.

Front

What does f(x) = x^2 + 2x + 5 represent?

Back

It represents a quadratic function.

Find f(-3) for the function f(x) = x^2 + 2x + 5.

Back

f(-3) = 8.

Front

What is the output of a function?

Back

The output of a function is the value that results from substituting an input into the function.

Front

If f(x) = 3x + 2, what is f(4)?

Back

f(4) = 14.

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 (y-values) that the function can produce.
