A company's daily profit, $P(x)$, in dollars, from selling $x$ units of a product is modeled by a quadratic function. The company achieves its maximum daily profit of $12,000$ dollars when it sells $200$ units. The company breaks even (profit is $0$) when it sells $100$ units and $300$ units. What was the company's initial cost (loss), in dollars, if no units were sold?
