Answer:

A. Reflect the graph of the first function across x-axis, translate it
(\pi)/(4) to the left, and translate it 2 units up.

Step-by-step explanation:

We have the original function is
y=\tan (x+(\pi)/(4))-1.

The new transformed function is given by
y=-\tan (x+(\pi)/(2))+1.

So, we can see that the following sequence of transformations have been applied to the original function:

1. The function f(x) is reflected about x-axis i.e. f(x) becomes -f(x), which gives
y=-\tan (x+(\pi)/(4))-1

2. This function obtained is translated
(\pi)/(4) units to the left i.e.
y=-\tan (x+(\pi)/(4)+(\pi)/(4))-1 i.e.
y=-\tan (x+(\pi)/(2))-1

3. Finally, this new function is translated 2 units upwards i.e.
y=-\tan (x+(\pi)/(2))-1+2 i.e.
y=-\tan (x+(\pi)/(2))+1

Hence, after applying, 'reflection across x-axis, translation of
(\pi)/(4) to the left, and translation of 2 units up', we get the required function.
