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

Answer:
x=-5, 7 are the excluded values
Step-by-step explanation:
Excluded values are the values that makes the denominator 0
To find excluded values we set the denominator =0 and solve for x
Factor x^2 - 2x - 35
(x-7)(x+5) =0
We set each factor =0 and solve for x
x-7 =0 so x= 7
x+5 =0 so x= -5
x=7, x=-5 makes the denominator 0
So x=7 , x=-5 are the excluded values
