    set the denominator equal to 0 and solve for x x^2+4x = 0 x = ?? or x = ??

    If the denominator of a fraction moves ever closer to zero as you move towards some value of x, then the result would be values of f(x) that will become ever larger as x gets closer to that value

    for instance here , if x^2 + 4x can be zero at any x value, the function will go off to huge numbers as you get closer to that x value, and that x value is not defined or in the domain of the function
