Does anyone know how to answer this? you!

Use question help, but with your own numbers. If you already tried that, though, Stay on here.

If I'm not mistaken you would use the Vertex formula which is (x= -b / 2(a)). Its the first part of the quadratic formula. This would help you find the maximum height of the object. It's been a semester since i've taken my last algebra class that I ever want to take in my life, but I don't want to tell you anything else because it may be wrong. I hope this helps you a little. I worked hours on end a day everyday on Math lab and I know how that working on line goes. I can feel your stress/ pain haha. Hope you figure it out.
