    so you can start by making a sketch... you need the asymptotes & intercepts on the axes...

    ofc you can but a sketch will help. You already know the vertical asymptote from the question. You can find the horizontal asymptote by seeing what happens as x tends to +-infinity. The function has the shape of a typical rational function .

    The range will then be all real values except the horizontal asymptote y value
