**Transcription for Educational Website**

The given function is:

\[ f(x) = \frac{110x - 11,000}{x - 140} \]

This function models the tax revenue, \( f(x) \), in tens of billions of dollars, in relation to the tax rate, \( x \). The graph associated with this function depicts how tax revenue decreases as the tax rate increases. At a tax rate of 100%, the government collects no revenue due to the absence of incentive for work, leading to zero income earned and zero tax revenue.

**Tasks:**

**a. Find \( f(30) \).**

\( f(30) = \) [Input field]

(Round to the nearest integer as needed.)

**Interpret your result. Choose the correct answer below.**

- A. When the tax rate is 65%, $300 billion in tax revenue is generated.
- B. If the tax rate increases to 85%, an additional $300 billion in revenue is generated.
- C. When the tax rate is 30%, $700 billion in tax revenue is generated.
- D. If the tax rate increases 30%, an additional $700 billion in revenue is generated.

**Identify the solution as a point on the graph. Choose the correct graph below.**

- Option A: (Graph depicting a certain point)
- Option B: (Graph depicting a certain point)
- Option C: (Graph depicting a certain point)
- Option D: (Graph depicting a certain point)

**b. Rewrite the function using long division to perform:**

\[ \frac{110x - 11,000}{x - 140} \]

(Simplify your answer. If there is a remainder, type your answer as \( \text{quotient} + \frac{\text{remainder}}{\text{divisor}} \).)

Then use this new form of the function to find \( f(30) \).

\( f(30) = \) [Input field]

(Round to the nearest integer as needed.)

**c. Is \( f(x) \) a polynomial function? Explain your answer. Choose the correct answer below.**

- Yes, it is a polynomial function because the numerator is not fully factored.
- No, it is not a polynomial function because it cannot be written in the form \( a_nx^n + a_{n-1}x^{n-1} + \
