1. What is the opening of the parabola? What does it imply regarding the value of a? 2. Identify the coordinates of the vertex. 3. Identify coordinates of any points on the parabola. 4. In the forn of quadratic function y = a * (x - h) ^ 2 + k , substitute the coordinates of the points you have taken in the variable x and y and the x- coordinate and the y-coordinate of the vertex in place of h and k respectively. 5. Solve for the value of a 6. Get the equation of the quadratic in the form of y = a * (x - h) ^ 2 + kby substituting the obtained h and k respectively. value of a and the x and y coordinates of the vertex
