WebbThis is a follow-up video about Parabola. This time, the discussion is about parabola that opens downward with vertex at (0,0). This video was recorded in IE... WebbTo work with parabolas in the coordinate plane, we consider two cases: those with a vertex at the origin and those with a vertex at a point other than the origin. We begin with the former. Let (x,y) ( x, y) be a point on the parabola with vertex (0,0) ( 0, 0), focus (0,p) ( 0, p), and directrix y =−p y = − p as shown in Figure 4.
WebbSince a = − 2 \goldD a=-2 a = − 2 start color #e07d10, a, end color #e07d10, equals, minus, 2, the parabola opens downward. This is enough to start sketching the graph. A coordinate plane. The x- and y-axes both scale by one. The graph is the function negative two times the sum of x plus five squared plus four. WebbThe standard form of a quadratic is Ax^2 +Bx +C = 0 if A is negative real number, then the parabola opens downward if A is positive real number 406 Consultants. 4.9/5 Star Rating …
