What is the oblique asymptote of the function f(x) = the quantity of x squared plus 7 x plus 11, all over x plus 5?

So its basically x^2+7x+11/ x+5 

You have to divide the denominator by the numerator. You can use synthetic division or long division. 

[-5] .    1 .    7 .    11
--------------------------
x + 2 + 1/x+5 

You ignore the remainder, therefore the answer is y = x+2
