Answer:
(a) 128 ft
(b) 4 s
(c) Vertex: (1, 144)
Step-by-step explanation:
Given information:
- h(t) = height in feet
- t = time in seconds after the launch
<h3><u>Part (a)</u></h3>
The height of the projectile at launch is the value of h(t) when t = 0 (the y-intercept).
Therefore, from inspection of the graph, the y-intercept is (0, 128).
So the <u>height of the projectile at launch is 128 ft</u>.
<h3><u>Part (b)</u></h3>
The length of time it took for the projectile to land is the time from the beginning (when t = 0) to when the height is 0 (the x-intercept).
From inspection of the graph, the x-intercept is (4, 0)
So the <u>length of time it took for the projectile to land is 4 s</u>.
<h3><u>Part (c)</u></h3>
The vertex is the turning point (minimum/maximum point).
Therefore, from inspection of the graph, the <u>vertex is (1, 144)</u>.
The vertex represents the time and height at which the projectile was at its maximum. So at the time of 1 second, the projectile was at its maximum height of 144 ft.
