Practice Test 7

A company’s profit is modeled by $P(x)=(x-1)(x-5)(x+2)$, where zeros represent break-even points. Which set lists all break-even x-values (zeros) and the corresponding x-intercepts?

Factor $$P(x)=x^2-5x+6$$ and use the zeros to sketch a rough parabola. Your sketch should show the x-intercepts and whether the parabola opens up or down.
