V. Activities For you to better understand, work on the activities that follow. - Activity A: Show Me in Another Way. Write the following quadratic functions into the vertex form and identify the coordinates of the vertex (h, k) of the parabola. Show your solutions. 1. y = 2x2 – 12x + 19 2. y = 3x2 + 6x - 1 3. y = x2 - 4x - 1 4. y = -2x2 - 4x - 5 5. y = -x2 + 8x – 14 = - 7​
