Answer:
The function is quadratic
Explanation:
The quadratic functions have the following form:
[tex]y=ax^2+bx+c[/tex]Where a, b, and c are constants.
In this case, the function that model the height of the ball can be rewritten as:
[tex]\begin{gathered} y=5+30x-4x^2 \\ y=-4x^2+30x+5 \end{gathered}[/tex]Since they have the same form where a = -4, b = 30, and c = 5, we get that the function is quadratic.
