Answer:
Direction : Open Down
Vertex : (3,4)
Focus : (3,15/4)
Axis of Symmetry : x=3
Directrix : y=17/4
x : 1,2,3,4,5
y : 0,3,4,3,0
Step-by-step explanation: Graph the parabola using the direction, vertex, focus, and axis symmetry. Graph is included down below!
Hope this helps you out! ☺
The common ratio is the multiplication of 2 each time. 5x2= 10// 10x2=20// 20x2=40

I only know this because I remember the common fractions, and 1/3 is .3333 repeating.
