Let +y+=+1%2F%28x%2B2%29+-7+
As +x-%3E+%2Binfinity+ then +x%2B2+-%3E+%2Binfinity+ so +1%2F%28x%2B2%29+-%3E+0+ and +y+-%3E+-7+
As +x-%3E+-infinity+ then +x%2B2+-%3E+-infinity+ so +1%2F%28x%2B2%29+-%3E+0+ and +y+-%3E+-7+

When +x%2B2-%3E0+ then +1%2F%28x%2B2%29+-%3E+infinity+ so +y+-%3E+infinity+

Hence the asymptotes are +y=-7+ and +x=-2+
