Which of the following equations is of a parabola with a vertex at (0, 3)? Оy (x-3) 2
Оун (х+3) 2
Оy 2-3
о у х2 + 3

Step-by-step explanation:

y=x²+3

vetex=(h,k) in the equation : ax²+bx+c

y=x²+3 ( a=1,b=0,c=0)

h=-b/2a=0

k=c=3

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
