Based on the the equations of the parabolas, identify each parabola whose focus and vertex lie in different quadrants.
mote1985 [20]

The equations of the parabolas whose focus and vertex lie in different quadrants will be:

  • x = -y²/16 - y/4 + 11/4 and
  • y = -x²/24 - 5x/12 + 95/24.

<h3>How to analyze the equations?</h3>

In the third equation, x = -y²/16 - y/4 + 11/4. The value of a = -1/16, b = -1/4, c = 11/4, and k = 3.

Also, in the sixth equation, y = -x²/24 - 5x/12 + 95/24. The value of a = -1/24, b = -5/12, c = 95/24, h = -5.

Therefore, the equations will be the third and sixth equations.
