Question

Equation of the plane crash: y=-3(x-1)^2+3

Answer the following questions in one sentence in a 5th graders response :

What is the vertex of the graph?

What does the vertex mean? (what is the highest point on the graph and what distance does it reach it?)


What distance does the plane crash hit the ground?

Answer 1

1) The vertex is at (1, 3).

2) The vertex is the highest point of the flight, so the plane reaches a height of 3 units when x = 1.

3) The plane hits the ground when y = 0, which happens at x = 0 and x = 2, so the crash points are 2 units apart.
