Final answer:
The domain of the function is (negative infinity, infinity) and the range is (5, infinity).
Step-by-step explanation:
In mathematics, the domain of a function refers to the set of all possible input values for which the function is defined. The range is the set of all possible output values that the function can produce.
The domain of a function is the set of all possible input values (x-values) and the range is the set of all possible output values (y-values) of the function.
In the given function f(x) = 3x + 5, the domain is (negative infinity, infinity) as there are no restrictions on the input values for x.
The range is (5, infinity) as the function will always produce a y-value greater than or equal to 5.
