## Homework Statement

State the amplitude, period, phase shift, and vertical shift:

##y=\frac{5}{2}sec\left(\frac{π}{x}-4π\right)-2##

## Homework Equations

## The Attempt at a Solution

[/B]

Amplitude:

Amplitude is equal to the absolute value of

*a*. So the amplitude here is ##\frac{5}{2}##

Vertical shift:

Down 2.

Phase shift and Period:

This is where I'm getting thrown off and it's because of the ##\frac{π}{x}## term.

How would I go about shaking this thing to get it into a more manageable form so that I can determine the phase shift and period? From all of the problems I've seen, x has had an integer or fractional coefficient, not been in the denominator like this.
