Or, graphically, if it looks like a bowl instead of a mountain. Explanation: Webb2 sep. 2024 · In parabolic curves, if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward. Now, we are given the equation of the parabola s; -36y = x². divide both sides by -36 to get; y = -x²/36. From the above it is clear that the leading coefficient is ...

Webb19 dec. 2024 · Your parabola will go on forever either up or down, so the end value of your range is always going to be ∞ (or −∞ if your parabola faces down.) This is good to know, because it means that half of the work of finding the range is already done for you before you even start calculating. If your parabola range ends at ∞, where does it start? cgtn china mega projectsWebbParabolas.
