Answer:
[-4 1 -2 - 7]
Step-by-step explanation:
[-1 - 2 4 8] + X = [-5 - 1 2 1]
X= [-5 - 1 2 1]- [-1 - 2 4 8]
X=[-5-(-1) - 1-(-2) 2-4 1-8]
X=[-4 1 - 2 - 7]

Answer:
y=-2x^2-4
Step-by-step explanation:
The parabola is wider than it's parent function, y = x^2. Therefore the coefficient, of x^2 (when you refer to quadratic equations it's a) should be greater than 1. Let's take 2.
y = 2x^2
Now it is reflected across the x-axis, so the equation turns to y = -2x^2. The vertex is shifted down 4. Note that it is shifted down, along the y-axis. This makes 'c' (again quadratic equations) -4.
Final Equation: y=-2x^2-4
