唔該曬！！！
更新1:
“y = x+a+1/(x+4)”，唔系x-4咩？ “4+2 = 4+a+1/(4-4)”，同埋1/0系冇意義呀··
我有條數學題唔識做，THX!!!!!!

✔ 最佳答案
答案：a = 2
圖片參考：http://imgcld.yimg.com/8/n/HA00108663/o/20130311114617.jpg
所以斜漸近線為 y = x + a，比較題目可得 a = 2

a=1
4+2=4+a(1)+1
4+2=4+a(1)+1

y = x+a+1/(x+4)
x+2 = x+a+1/(x-4)
4+2 = 4+a+1/(4-4)
6 = 4+a+0
a = 2

x+4係我打錯左sorry
x+2 = x+a+1/(x-4)
4+2 = 4+a+1/(4-4)
6 = 4+a+0
a = 2
