#3 isn't clear.

1) Start with the basic function.

2) Rewrite to expose the characteristics.

3) Redraw with one characteristic at a time.

The first

y = tan (2( + /2)) + 1

y = tan (2( - (-/2))) + 1

y = tan () -- Draw this

y = tan () -- Draw this. What happens to the PERIOD?

y = tan (2( - (-/2))) -- Draw this. What happens HORIZONTALLY?

y = tan (2( - (-/2))) + 1 -- Draw this. What happens VERTICALLY?

Go for it!
