You can put this solution on YOUR website! Perform the division. You will find a quotient and a remainder. The denominator to use with the remainder will be (x-2). The quotient for this rational expression is .
What happens to this expression as x tends to negative infinity without bound? What happens to this expression as x tends to positive infinity without bound? In both cases, the 7/(x-2) becomes increasingly small, and either positive or negative, but its absolute value becomes increasingly small. The other part, 2x+1 persists and is a slant asymptote, a line which the function approaches but never reaches.
And actually to show the asymptote with the function,
