Answer:
A parabola opens downward with vertex at (1,20)
Step-by-step explanation:
The function that models the height of bag of candies is
[tex]h(t) = - 16 {t}^{2} + 32t + 4[/tex]
The graph of this function is a parabola that opens downward.
To find the maximum height of the candy bag, we complete the squares to obtain the vertex form of the function.
Factor -16 to get;
[tex]h(t) = - 16( {t}^{2} - 2t) + 4[/tex]
Add and subtract the square of half the coefficient of t.
[tex]h(t) = - 16( {t}^{2} - 2t + 1) + 16+ 4[/tex]
Factor the perfect square trinomial:
[tex]h(t) = - 16( {t - 1)}^{2} + 20[/tex]
The vertex is (1,20)
This means the maximum height after 1 second is 20 feet.
