Step-by-step explanation:
the maximum height is the y-value of the vertex.
h(x) = -2x² + 20x + 48
<em> a=-2, b=20, c=48</em>
![x = \frac{-b}{2a} = \frac{-20}{2(-2)} = \frac{-20}{-4} = 5](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-b%7D%7B2a%7D%20%3D%20%5Cfrac%7B-20%7D%7B2%28-2%29%7D%20%3D%20%5Cfrac%7B-20%7D%7B-4%7D%20%3D%205)
h(5) = -2(5)² + 20(5) + 48
= -50 + 100 + 48
= 50 + 48
= 98
