Answer:
-x^2 - 6x -5
Step-by-step explanation:
Approximatly speaking, this parabola is -x^2 + 4 but it was moved 3 to the left.
We know that when we move something to the left 3 units we replace x with (x+3)
Let's replace this with (x+3)
-(x+3)^2 + 4 -> -(x^2+6x+9)+4 -> -x^2 - 6x -9 + 4 -> -x^2 - 6x -5
