I am looking to find the following things is there an easy way to find each of these with out ploting?

the attenuation (in dB) at the Nyquist frequency? pass-band peak value (linear scale)

Assume the edge of the passband is the highest frequency where attenuation does not exceed 2dB. passband frequency (to nearest tenth)

Assume the edge of the stop-band is the point where attenuation exceeds 10dB. stopband frequency (to nearest tenth)
