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

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.

Answer 2

Answer:

76ft.
