Function Notations Practice

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols. It typically uses the format f(x), where 'f' is the name of the function and 'x' is the input variable.

Front

What does f(2) represent in function notation?

Back

f(2) represents the output of the function f when the input is 2.

Front

What are the inputs of a function called?

Back

The inputs of a function are called 'domain' or 'independent variables'.

Front

What are the outputs of a function called?

Back

The outputs of a function are called 'range' or 'dependent variables'.

Front

Given f(x) = -x + 12, find f(-2).

Back

f(-2) = -(-2) + 12 = 2 + 12 = 14.

Front

If f(x) = -5x + 10, find f(3).

Back

f(3) = -5(3) + 10 = -15 + 10 = -5.

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.

Front

What is the domain of a function?

Back

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

Front

How do you find the output of a function?

Back

To find the output of a function, substitute the input value into the function's equation and simplify.

Front

What does it mean if a function is undefined at a certain point?

Back

A function is undefined at a certain point if there is no output value for that input, often due to division by zero or taking the square root of a negative number.
