Q. In which direction does the parabola y−9x2=0y - 9x^2 = 0 open?\newlineChoices:\newline(A)up\newline(B)down\newline(C)right\newline(D)left
  1. Identify Parabola Type: y−9x2=0y - 9x^2 = 0\newlineIdentify if the parabola is vertical or horizontal.\newlineSince the xx term is squared, it's a vertical parabola.
  2. Isolate yy in Standard Form: y−9x2=0y - 9x^2 = 0\newlineIsolate yy to get the standard form.\newliney=9x2y = 9x^2
  3. Determine Opening Direction: y=9x2y = 9x^2\newlineDetermine the direction of the opening.\newlineThe coefficient of x2x^2 is 99, which is positive, so the parabola opens up.
