To find the domain and range for the function ( f(x) = 2x + 4 ):
Domain: The domain of a function is the set of all possible input values (x-values) for which the function is defined. Since ( f(x) = 2x + 4 ) is a linear function, it is defined for all real numbers. Therefore, the domain is ( \mathbb{R} ) (all real numbers).
Range: The range of a function is the set of all possible output values (y-values) that the function can produce. For the function ( f(x) = 2x + 4 ), as ( x ) varies across all real numbers, the expression ( 2x + 4 ) will also vary across all real numbers. Hence, the range is also ( \mathbb{R} ) (all real numbers).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
