Find the equation of the parabola in vertex form having a vertex of (2,4) and a y-intercept of (0,2)

Step-by-step explanation:

The vertex form of a parabola:

(h, k) - vertex

We have the vertex (2, 4). Substitute:

The y-intercept (0, 2). Put the coordinates of the y-intercept to the equation:

          subtrzct 4 from both sides

          divide both sides by 4
