Answer: x = 0
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Vertex = (3, 5)
focus = (3, 7)
directrix is y = 3
Answer:

Step-by-step explanation:






F(x) = -2(x + 3)^2 - 1
vertex = (-3, -1)
domain is all real number values of x and
range is all real numbers values of y less than or equal to -1.
