Graph Transformation Question I get that because x^2 will be negative the answer will be one of the following a, b, or e. But I don't understand why the answer is a??


$y = -(x + a)^2 = -(x - [-a])^2$
The first minus means that the graph concaves downward. This rules out (c) and (d).
Inserting the middle minus is a way to find the root, which is $[-a]$.
Since $a > 0, -a$ is some negative quantity. This leave (a) as the only choice.
