Stefan works as a pizza chef. He begins his day by preheating the pizza oven. Today, the oven's interior temperature was 72°F when Stefan turned it on high-power to preheat. The temperature rose steadily at a rate of 12°F per minute until it reached its ideal temperature an hour later. Then, Stefan reduced the power so the temperature would stop rising. The function T(m) represents the oven's interior temperature, in °F, after m minutes of preheating. What is the domain?
