Answer for P14.9

The magenta line is the Bode plot that you should have constructed from the circuit parameters shown in the problem statement. The black line shows the roll-off of open loop gain typical for op amps. The red line shows the exact form of the frequency dependence of the bass-boost circuit, with breakpoints at 44 Hz and 400 Hz.

From a MathCAD document (with edited graph):
