Final answer:
Domain: The domain of the given function y = -22 + 4 - 3 is the set of all real numbers since there are no restrictions on the input values x.
Range: The range of the function y = -22 + 4 - 3 is {−21}, represented as a single value, as the expression simplifies to a constant.
Step-by-step explanation:
The domain of a function refers to the set of all possible input values (x) that the function can take. In the given function y = -22 + 4 - 3, there are no restrictions or limitations on the input values x. Thus, the domain includes all real numbers, indicated by the symbol (-∞, ∞).
Regarding the range of the function, it's important to simplify the expression to understand the possible output values (y). Simplifying the given function, y = -22 + 4 - 3 results in y = -21. This simplification reduces the entire expression to a constant, which means that no matter what the input is, the output will always be -21. Therefore, the range of the function is {−21}, representing a single value.
In summary, the domain consists of all real numbers (-∞, ∞) since there are no restrictions on the input values. Meanwhile, the range of the function is a single value, {-21}, as the expression simplifies to a constant output of -21, independent of the input. Therefore, the correct answer is not specifically listed among the options provided, but the closest match would be "e) (−[infinity],−3)" if -21 were erroneously replaced with -3 in the options.
