Answer:
The ball goes 14 meters high
Step-by-step explanation:
Given the function
y= -0.1x^2 + 2x + 4
In the figure attached, the function is shown.
The maximum height is equivalent to the vertex of the function, which is obtained as follows:
Xv = -b/(2a) = -2/(2*-0.1) = 10
Yv = -0.1Xv^2 + 2Xv + 4
Yv = -0.1(10)^2 + 2(10) + 4 = 14
