Algebra 1 EOC Quadratics

A local company makes giant bags of pork rinds. Based on their records, their daily profit is modeled by f(x) = x² + 3x - 19 where x is the number of bags of pork rinds made. If f(x) is negative, it means the company has lost money. What is the LEAST number of bags of pork rinds need to be made in order to make a profit?

• 3

• 4

• 7

• 19
