Part A- The vertex form of the question of horizontal parabola is given x=1/4p(y-k)^2+h, where (h, k) is the vertex of the parabola and the absolute value of p is the distance from vertex to focus, which is also the distance from the vertex to the directrix. You will use GeoGebra to create a horizontal parabola and write the vertex form of its equation. Open GeoGebra and complete each step below. Mark the focus of the parabola you are going to create at F(-5,2). Draw a vertical line that is 8 units to the right of the focus. This line will be the directrix of your parabola. What is the equation of the line?
