Best ResponseYou've already chosen the best response.0a. −5 ≤ x ≤ 20 b. 0 ≤ x ≤ 15 c. x ≥ 0 d. All real numbers I'm really not sure what the answer is. I think it's A but another post said B, so I'm just confused. I suck at determining domains.

Best ResponseYou've already chosen the best response.1domain set of values 0 to 15 yes 15 included because it y at least 200 when x = 15 y = 200 at least means the lowest value allowed and includes what is more than that value
