Answer:
(b) Domain: all real numbers; Range: {-24}
Explanation:
You want the domain and range of the function f(x) = -24.
Domain
The domain of the function is the set of values of x for which it is defined. The function f(x) is defined for all x, so the domain is all real numbers.
Range
The range is the set of output values of the function. This function has only one output value: -24. The range of the function is {-24}.
