Answer
See graph below
Work Step by Step
For $y=a\csc c(x−h) + k$
Amplitude: $|a|$, Period: $\frac{2\pi} {|c|}$,
Horizontal Shift: h
The question asks for a graph with an appropriate viewing rectangle, so we must calculate the period and then add it to the horizontal shift
Given $f(x) = \csc 40x$
The Amplitude is $|1| =1$
The Period is $\frac{2\pi}{|40|} = \frac{\pi}{20}$
The Horizontal shift is 0 units to the right
The appropriate viewing rectangle would be from $[0, \frac{\pi}{20}]$
