  1. x = -2, 3 and 5 are the real roots.

    There are also complex roots x = 3 + i and 3 - i.

    The function f(x)=x^2+5x+6 has zeros at -2 and -3. What are the zeros of the function y=-2f(x/11) ? Do you just plug x/11 into each x value in f(x)? Like f(x)= (x/11)^2+5(x/11)+6 (I exclueded the -2 because if I divide 0 by -2,
