, where

*is the height in meters off the ground and*

*is the horizontal distance in meters from Robbie.*

Use either the Zero Product Property or the Quadratic Formula to find the

-intercepts of the path of Robbie’s rocket. What do the -intercepts tell you? orCoordinates:

and Robbie backed up

m from the launch pad.

The rocket landedm away from him.perty or the Quadratic Formula to find the -intercepts of the path of Robbie's rocket. What do the-intercepts tell you?When Robbie's rocket lands, how far is it from the launch pad?

The launch pad was 5m from Robbie, and the rocket landed 8m from him in the same direction.
