The problem in the image asks for the solution of the difference \(\Delta f\) between the points \(P\) and \(Q\) when the function \(f\) is defined as \(f(x) = 5x\).

The problem is likely asking for the difference in the function's values at two points, \(P\) and \(Q\). Let's solve it step by step.

Given:

\[
f(x) = 5x
\]

Let's assume the points \(P\) and \(Q\) correspond to two values of \(x\), say \(x_1\) and \(x_2\).

The difference \(\Delta f\) is calculated as:

\[
\Delta f = f(x_2) - f(x_1) = 5x_2 - 5x_1 = 5(x_2 - x_1)
\]

Now, let's consider the options given:

- Option \(a\) corresponds to \(\Delta f = 4.25x\).
- Option \(b\) corresponds to \(\Delta f = 18.25x\).
- Option \(c\) corresponds to \(\Delta f = -4.25x\).
- Option \(d\) corresponds to \(\Delta f = 225x - 12\).

To identify the correct answer, it is necessary to know the specific values for \(x_1\) and \(x_2\). Without this, the general form of the difference \(\Delta f = 5(x_2 - x_1)\) must be used.

Unfortunately, these values aren't provided in the image or problem statement, and we need them to determine the exact value of \(\Delta f\). If you have more context or if there's something missing from the image, please provide that, and I can offer more help!

Would you like details on this, have any questions, or perhaps need to look into a different aspect of the problem?
