Trying to figure out how to do these

    asymptotes horizontal and vertical

    f(x)= 2x+3/x+2

    What values of x makes denominator zero? Do you have to ignore anything?

    In order to DO them right, first WRITE them right!

    What you wrote is f(x)= 2x+(3/x)+ 2 and f(x)=(x/x^2)+ 1 but what you really MEANT was f(x)= (2x+ 3)/(x+ 2) and f(x)= x/(x^2+ 1).

    How to do them? Start by looking up the definitions of horizotal asymptote and vertical asymptote.

    do you mean f(x) = 2x + (3/x) + 2 and f(x) = (5x/x^2) + 1


    do you mean f(x) = (2x + 3)/(x + 2) and f(x) = 5x/(x^2 + 1)

    Please clarify....
