    Where does the graph y=x+1/x+2 cross the coordinate axes?

    Where does the graph y=x+1/x+2 cross the coordinate axes? Can you please explain what the question means and how to do it. Thanks

    Solution(s) to equation y(x)=0 is the answer. x for which function y(x) has the same values as x axis y=0.

    I assume you mean y=(x+1)/(x+2)? Or perhaps y=x+[1/(x+2)]? Who knows ....

    It surprises many people when they are told that using brackets is important if you do not want your mathematical expressions to be ambiguous.

    I'm guessing the equation is:

    y=\frac{x+1}{x+2}

    I think the question is asking where the graph hits the x axis and the y axis at x = 0 and y = 0.

    To do this, you substitute y = 0 and solve for x. This will give you the x-intercept.
    Substitute y = 0 and solve for y and this will give you the y-intercept.
