Answer:
36; 18; -35; 0
Step-by-step explanation:
They break even again when their profit is zero, i.e. at the x-intercept (36).
The worst case scenario is when their profit is the lowest, i.e. at the minimum vertex where they produce 18 items for a profit (in this case loss) of -35 dollars.
The first root tells us that the profit will be zero when zero products are produced.
