Find the vertex of the parabola y = 8x2.

murzikaleks [220]

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)

If someone could please help me, I want to make sure that the steps are correct.

Leya [2.2K]

Your answer would be the last option, c = √(E/m).

We can see this when we rearrange the equation, as:

E = mc²
÷ m
E/m = c²
√
√(E/m) = c

So you got all the steps in rearranging correct :)

I hope this helps!
