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 
0.4(420) = 4(420)/10
(0.4 is essentially 4/10)
1680/10 = 168
