Final answer:
The values that are not represented by the quotient (f/g)(x) include x = 9 since g(x) would be zero, causing division by zero, which is undefined. Other exclusions or specific values not represented would depend on additional context or constraints provided by the question.
Step-by-step explanation:
To find values that are not represented by the quotient of the functions f(x) and g(x), we first need to determine the functions themselves. Given that f(x) = (1 + x)(5 + x) and g(x) = 9 - x, the quotient can be represented by (f/g)(x) = f(x)/g(x). We must consider the values that make g(x) equal to zero because these would make the quotient undefined. Specifically, when x = 9, g(x) is 0, and therefore cannot be 9 since we cannot divide by zero. Moreover, the value of cannot be less than 5% of 0.50 in this context as this does not relate to finding the values that are not represented by the quotient (f/g)(x).
The quadratic formula is not necessary for determining these values, because we are not solving for in the equation f(x) = g(x); rather, we are finding values of x that we should exclude to avoid division by zero or other constraints imposed on the functions.
