(1) Suppose that we have a directrix a: = "a and a. focus F(a, 0). Find the set of points P[:r:, y) so that PF equals the distance from P to the directrix. (2) Consider a general parabola, y : as;2 + bx + c. By completing the square, show that this parabola. can be obtained from the parabola y 2 $2 by 1) a. vertical stretch (i.e., a. map that sends (my) to (2:, Icy) for some constant k), a horizontal translation, and a. vertical translation. For question [2 ] Just complete the square and identify which portions are the stretches and translations
