You just simplify the fraction (so, 8/6 which is 4/3)
So your comes 4(square root of 35)/ 3 (square root of 15)
3/5 is bigger because 4/7 = 20/35 and 3/5 = 21/35
Answer:

Step-by-step explanation:
Hi there!
Because we're given the vertex of the parabola, we can determine its equation in vertex form:
where the vertex is 
Plug in the vertex (0,0)

Now, we must solve for a. Plug in the given point (-2,3) and solve for a:

Therefore, the value of a is
. Plug this back into
:

I hope this helps!
