1 answer:
Answer:
Domain: All real numbers
Range:
Step-by-step explanation:
The domain is the set of all x values. The quadratic equation continue to operate over all x-values in both directions. The domain is all real numbers.
The range is the set of all y-values. Here the quadratic begins at -3 and continues in a downward direction forever. Then range is
