Which of the following equations is of a parabola with a vertex at (0, 3)? y = (x - 3) 2 y = (x + 3) 2 y = x 2 - 3 y = x 2 + 3

Option D.

Step-by-step explanation:

We have to find the equation of the parabola which has vertex at ( 0,3 )

If we write the equation of a parabola in the vertex from then we will write

y = ( x - h )² + (k)²

In this equation ( h, k) will be the vertex.

(a) y = (x-3)² + 0

    so ( 3,0) will be the vertex

(b) y = ( x+3)² + 0

   or y = [x - (-3)]² + 0

   then ( -3,0) will be the vertex

(c) y = (x² - 3)

   y = ( x-0 )² + (-3)

  then ( 0, -3) is the vertex.

(d) y = x² + 3

    y = ( x-0 )² + 3

Then ( 0, 3 ) will be the vertex of this parabola.

Option D. is the answer.
