What are the zeros (roots) of the function 2x/((x^2)-1) ? Would it just be (0,0)?

Thanks in advance!

  • AP Calc -

    since f(x) is a rational function, f(x)=0 where the numerator is zero (as long as the denominator is not also zero).

    so, when is 2x=0?
    Your answer is correct (almost). A zero is an x-value where y=0. So, the zeros here are just x=0.
