X None of these characteristics are true for all linear, exponential, and quadratic functions. Each type of function has its own unique characteristics.
O The domain of the function is all real numbers.
Yes, this characteristic is true for all linear, exponential, and quadratic functions. The domain of a function is the set of all possible input values (x-values), and for linear, exponential, and quadratic functions, the domain is indeed all real numbers.
