Q. In which direction does the parabola y+10x2=−1y + 10x^2 = -1 open?\newlineChoices:\newline(A)up\newline(B)down\newline(C)right\newline(D)left
  1. Identify Parabola Orientation: Identify if the parabola is vertical or horizontal.\newliney+10x2=−1y + 10x^2 = -1 has a squared xx term.\newlineIt's a vertical parabola.
  2. Rearrange Equation to Standard Form: Rearrange the equation to standard form by isolating yy.\newlineSubtract 10x210x^2 from both sides.\newliney+10x2−10x2=−1−10x2y + 10x^2 - 10x^2 = -1 - 10x^2\newliney=−10x2−1y = -10x^2 - 1
  3. Determine Parabola Opening Direction: Determine the direction the parabola opens.\newlineThe coefficient of x2x^2 is −10-10, so a=−10a = -10.\newlineSince a<0a < 0, the parabola opens downwards.
