Question

A linear function and a quadratic function both have a domain of all real numbers.

True
False
?

Answer 1

true....
the range of the function shows all real values

Answer 2

Answer: True

Explanation: The domain of a quadratic function in standard format is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.

Linear function is almost always going to be all real numbers. The range of a non-horizontal linear function is all real numbers no matter how flat the slope might look.
