Answer:
D.
Step-by-step explanation:
For f(x), which has a vertex at (2,0), the y-intercept at (0,4) is above this vertex, so the parabola opens upward. This means that the vertex is the only point that touches the x-axis, so there is only 1 x-intercept.
For h(x), the graph does not have any x-intercepts.
For g(x) = x^2 + x - 2 = (x+2)(x-1), this intersects the x-axis at x = -2 and x = 1, so there are 2 x-intercepts.
From least to greatest: h(x), f(x), g(x).
H'=-32t+96
0=-32t+96
-96=-32t
3=t
3 seconds
H=-16t^2+96t+3
H=48^2+288+3
H=48^2+291
