You can put this solution on YOUR website!

F%28x%29=x%5E2-2
vertex form is: F%28x%29=%28x-0%29%5E2-2=> h=0,k=-2
so, vertex is (0,-2)
axis of symmetry: y-axis
table of 5 points:
x|y......use vertex as one point, and choose x values and calculate y
0|-2
1|-1.....F%281%29=%281%29%5E2-2=>F%281%29=-1
-2|2.....F%28-2%29=%28-2%29%5E2-2=>F%28-2%29=2
3|7.....F%283%29=%283%29%5E2-2=>F%283%29=7
-4|14.....F%28-4%29=%28-4%29%5E2-2=>F%28-4%29=14
graph: plot these point and draw parabola through
