Question

The function f(x) = −16x2 + 112 models the height, in feet, of an

object x seconds after it was released. What was the height of the
object 1.5 seconds after it was released?

Answer 1

76ft.

Explanation:

Answer 2

For this, just plug in 1.5 into the x variable of this function and solve as such:

`f(1.5)=-16*1.5^2+112\\f(1.5)=-16*2.25+112\\f(1.5)=-36+112\\f(1.5)=76`

The height of the object was at 76 ft.
