Answer:
Domain = all real numbers
Range = y ≥ -4
Explanation:
Domain is the x-values, and for parabolas it is almost always all real numbers.
Range is the y-values, and the lowest it gets is -4.
The f(x) domain is the set of all values for the function and the function spectrum is the set of all values for which f is defined.
