Just need help on graph. Plz explain if you can. I have a few more questions like this.

Vertex-either the highest point or lowest depending on which way the parabola is (-1,-9)
Y- int- where the graph intersects the y int- (0,-8)
X- int- where the graph intersects the x int- (-4,0) and (2,0)
axis of symmetry- where the line could be folded in half and be the same- x=-1
equation: (x-1)^2 -9=y
