Answer:
420
Step-by-step explanation:

Good luck and I hope this helps :)
Domain:
We know that domain is all possible values of x for which any function exists
or all possible values of x for which curve is defined
we can see that curve extended from left to right side
so, domain is all real numbers
Range:
We know that domain is all possible values of y for which x is defined
or all possible values of y for which curve is defined
we can see that lowest y-value is 0
and upper most value is inf
so, range is
so, option-D.............Answer
