brooklyn launches a toy rocket from a platform. the graph below shows the height of the rocket h in feet after t seconds. what is the rockets greatest height?
Answer
Explanation:
Step1: Identify the vertex of the graph
The graph of the rocket's height is a parabola. The vertex of a parabola represents the maximum or minimum value. For a parabola opening down - ward (which is the case here as the rocket goes up and then comes down), the vertex gives the maximum height.
Step2: Read the y - coordinate of the vertex
The vertex of the given parabola is the point $(1.75,121)$. The y - coordinate of the vertex represents the maximum height of the rocket.
Answer:
121 feet
