Answer:
x-intercept means the advertising expense when the company's profit was zero dollars ⇒ D
Step-by-step explanation:
Let us solve the question
∵ P = -250x³ + 1,505x² - 300, for 0 < x < 6
∵ P is the profit in tens of thousands of dollars
∵ x is the advertising expense in tens of thousands of dollars
∴ x is the independent variable
∴ P is the dependent variable
→ x-intercept means value x when P is 0
∵ The x-intercept is the value x at P = 0
∴ x-intercept means the advertising expense when the company's
profit was zero dollars
