Are a and b the same? also it's A
For the solid line it is (0,-3), (0,3), (-3,4)
for the dotted line it is (-1,-1), (-3,-2), (-3,2)
hope this helps don't know for sure though if its right i just did the best i could do.
Yes it is 2D Your welcome
The second degree polynomial with leading coefficient of -2 and root 4 with multiplicity of 2 is:
![p(x) = -2*(x - 4)*(x - 4) = -2*(x - 4)^2](https://tex.z-dn.net/?f=p%28x%29%20%3D%20-2%2A%28x%20-%204%29%2A%28x%20-%204%29%20%3D%20-2%2A%28x%20-%204%29%5E2)

How to write the polynomial?</h3>
A polynomial of degree N, with the N roots {x₁, ..., xₙ} and a leading coefficient a is written as:
![p(x) = a*(x - x_1)*(x - x_2)*...*(x - x_n)](https://tex.z-dn.net/?f=p%28x%29%20%3D%20a%2A%28x%20-%20x_1%29%2A%28x%20-%20x_2%29%2A...%2A%28x%20-%20x_n%29)
Here we know that the degree is 2, the only root is 4 (with a multiplicity of 2, this is equivalent to say that we have two roots at x = 4) and a leading coefficient equal to -2.
Then this polynomial is equal to:
![p(x) = -2*(x - 4)*(x - 4) = -2*(x - 4)^2](https://tex.z-dn.net/?f=p%28x%29%20%3D%20-2%2A%28x%20-%204%29%2A%28x%20-%204%29%20%3D%20-2%2A%28x%20-%204%29%5E2)
