Reference answer:

Gain graph Based on the derived formula, the gain part graph can be obtained according to the change of frequency f;

Gains:

But how is the phase diagram obtained?

Phase:

Is the phase formula determined by the former or the latter? Or is it determined by other methods?

"But how do you get the phase diagram?"

The phase is also "based on the derived formula and the change in frequency f".

In your reference answer, expand the parallel equation R2||(1/jwC) in the first equation after "F=" into [R2*(1/jwC)]/[R2+(1/jwC)], and then try to write the complex fraction in the form of the second equation after "F=", and you can get the two transition frequencies.
