Solution Steps

To find the inverse function \( p^{-1}(x) \) of \( p(x) = \frac{12}{4x + 11} \), we need to solve for \( x \) in terms of \( y \) where \( y = p(x) \). Then, we will express \( x \) as a function of \( y \). After finding the inverse function, we will determine the domain and range of both \( p(x) \) and \( p^{-1}(x) \).

Solution Approach
  1. Start with \( y = \frac{12}{4x + 11} \).
  2. Solve for \( x \) in terms of \( y \).
  3. Express \( x \) as a function of \( y \) to get \( p^{-1}(x) \).
  4. Determine the domain and range of \( p(x) \) and \( p^{-1}(x) \).
Step 1: Finding the Inverse Function

To find the inverse function \( p^{-1}(x) \) of \( p(x) = \frac{12}{4x + 11} \), we start with the equation: \[ y = \frac{12}{4x + 11} \] Rearranging this equation to solve for \( x \) gives: \[ x = -\frac{11}{4} + \frac{3}{y} \] Thus, the inverse function is: \[ p^{-1}(x) = -\frac{11}{4} + \frac{3}{x} \]

Step 2: Domain of \( p(x) \)

The function \( p(x) \) is undefined when the denominator equals zero: \[ 4x + 11 = 0 \implies x = -\frac{11}{4} \approx -2.75 \] Therefore, the domain of \( p(x) \) is: \[ \text{Domain of } p(x): \quad x \neq -\frac{11}{4} \]

Step 3: Range of \( p(x) \)

The range of \( p(x) \) excludes the value where the function approaches zero: \[ \text{Range of } p(x): \quad y \neq 0 \]

Step 4: Domain of \( p^{-1}(x) \)

The domain of the inverse function \( p^{-1}(x) \) corresponds to the range of \( p(x) \): \[ \text{Domain of } p^{-1}(x): \quad x \neq 0 \]

Step 5: Range of \( p^{-1}(x) \)

The range of the inverse function \( p^{-1}(x) \) corresponds to the domain of \( p(x) \): \[ \text{Range of } p^{-1}(x): \quad y \neq -\frac{11}{4} \]

Final Answer

\[ p^{-1}(x) = -\frac{11}{4} + \frac{3}{x} \] \[ \text{Domain of } p(x): \quad x \neq -\frac{11}{4} \] \[ \text{Range of } p(x): \quad y \neq 0 \] \[ \text{Domain of } p^{-1}(x): \quad x \neq 0 \] \[ \text{Range of } p^{-1}(x): \quad y \neq -\frac{11}{4} \]

Thus, the final boxed answers are: \[ \boxed{p^{-1}(x) = -\frac{11}{4} + \frac{3}{x}} \] \[ \boxed{\text{Domain of } p(x): x \neq -\frac{11}{4}} \] \[ \boxed{\text{Range of } p(x): y \neq 0} \] \[ \boxed{\text{Domain of } p^{-1}(x): x \neq 0} \] \[ \boxed{\text{Range of } p^{-1}(x): y \neq -\frac{11}{4}} \]
