the first x is odd so the equation intersects at the o and the other one is at 2

The function is a(x)=x(x+2)². If you have to find the zeros, you have to solve x(x+2)²=0. What are the solutions?

The zeros are 2 and 0. Because of the multiplicity (2) of 2, there is no sign change if you pass 2. If the leading term is x^3, there is a sign change when you pass 0. I think you already did well!
