Answer
See graph below.
Work Step by Step
For $y=a\tan c(x−h) + k$
Amplitude: $|a|$, Period: $\frac{\pi} {|c|}$,
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 $f(x) = \tan 25x$
The Amplitude is $|1| =1$
The Period is $\frac{\pi}{|25|} = \frac{\pi}{25}$
The Horizontal shift is 0 units to the right
For tangent, the center of the viewing rectangle will be at 0, and half of the period will be added on the positive and negative side.
The appropriate viewing rectangle would be from $[-\frac{\pi}{50}, \frac{\pi}{50}]$
