Easy graph question, i hope

  1. Dec 10, 2008 #1
    i have two graphs, i need to know how to calculate the points where the two graphs touch.

    in my case there are two points.

    do i have to make the equation equal or something?

    the two equations are (7x)/(x^2+1)

    and (x^2+2x+5)/(x+2)

    Welcome to PF.

    You mean that you have 2 equations Y(x).

    And you want to identify where the values of Y are equal between the 2 equations.

    Maybe if you set one = to the other and solved for x ...?
