Amplitude = None, Period =

#### Explanation:

Use the standard form

Amplitude = a, Period =

Given equation is

Since the graph of the function sec does not have a maximum or minimum value, there can be no value for the amplitude.

Amplitude = none

Period

Phase shift = c / b = 0 as ( c = 0)

Vertical shift = d = 0.
