Respuesta :
The vertex = (-2,-4)
One of the points = (0,-8)
SOLUTION:
General formula to make vertex form equation
(h,k) is the vertex
y = a(x - h)² + k
Solve the equation
y = a(x - h)² + k
-8 = a(0 - (-2))² + (-4)
-8 = a(0+2)² - 4
-8 = 4a - 4
-4 = 4a
a = -1
The equation should be
y = -1(x - (-2))² + (-4)
y = -1(x + 2)² - 4
y = -(x + 2)² - 4
The answer is fourth option
