Using your calculator to do a quadratic regression, express the height of the object as a function of the number of seconds that have passed since the object was thrown.

Round all numbers to 1 decimal place.

Using your quadratic regression, how high will the object be 2.8 seconds after it is thrown?

Round to 3 decimal places.

Using your quadratic regression, how long will it take the object to reach 31 meters?
