Question

The graph of which equation has a vertex of (3, 0)?

y = (x + 3)2

y = (x – 3)2 + 3

y = 2(x + 3)2

y = 2(x – 3)2

Answer 1

I think C?

Answer 2

is the )2 mean )^2?

Answer 3

Yes, sorry! I keep doing that

@jjharley
ok, so the 'vertex form' of a parabola is:
y = a(h-x)^2 + k
where the term h and k are the vertext of the equation.
so go through each of the possible solutions, foil them. then simplify them to look like the 'vertext form' then. pick out the h, k of each equaiton and see which one has the point (3,0) in it
make sense? ya, no?
