Incomplete Equation Query
To solve the equation provided in the image, you need to substitute x with the given value or perform the operation defined. However, the image contains an equation for a function \( f(x) \), but it does not specify what needs to be solved for. The equation given is:
\[ f(x) = px^3 - 3px^2 + x - 4 \]
Since the question appears to be cut off at the right edge, I cannot see the complete instructions. Could you please provide the full question or tell me what you need to solve for regarding the function \( f(x) \)?
