Question

Which of the following equations is of a parabola with a vertex at (0, 3)?

Answer 1

The equation that is of a parabola with a vertex at (0, -3), is $y=x^2+3$.

Answer 2

Parabola has a vertex at: ( 0, 3 )
h = 0, k = 3;
y = a ( x - h )² + k
a = 1
y = ( x - 0 )² + 3
y = x² + 3
Answer:
The parabola with a vertex at ( 0, 3 ) is : y = x² + 3
