Question

A cannonball is shot straight up into the air. The height of the cannonball at time t is represented by the function f(t)=−16t^2+40t+3 .

What does the 3 represent?

the initial velocity of the cannonball

the initial height of the cannonball

the time when the cannonball hits the ground

the maximum height of the cannonball

Answer 1

Answer:

the initial height

Step-by-step explanation:

given the height is represented by the function

f(t) = - 16t² + 40t + 3

Then the initial height is when t = 0, that is

f(0) = 0 + 0 + 3 = 3 ← initial height
