Fireworks are launched from a platform 15 feet off the ground. A fountain firework and a pinwheel firework are launched at the same time. The height o the fountain firework and a pinwheel firework are launched at the same time. The height of the fountain firework at different times is shown below. *
The height of the fountain firework can be described by the function h(t) = -3t^2+ 12t + 15, where 'h' represents height and 't' represents the number of seconds since the firework was launched. Explain how you know that this graph accurately represents the equation for the interval shown.
