Answer:
vertex is at (0,0)
Step-by-step explanation:
Find the vertex of the parabola y = 8x2.
I assume you meant y = 8* x^2
this can be compared to the general vertex form y = a (x - h)^2 + k
where vertex at (h, k)
so then...
h =0 and k = 0 here
vertex is at (0,0)
0.8 is 20% of 4. This is because 20% of something occurs when something is divided by 5, since it is 1/5 of 100. You multiply 0.8*5, and you get 4.
Step-by-step explanation:

from difference of two squares:
