Domain & Range

Front

What is the definition of Domain in a function?

Back

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

Front

What is the definition of Range in a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the domain?

Back

D: {-4, 0, 1, 2}.

What is an example of a function with a limited domain?

Back

f(x) = 1/x, where x cannot be 0.

Front

What is an example of a function with a limited range?

Back

f(x) = x^2, where the range is y >= 0.
