A rocket is shot straight up into the air is F(t) represents the height in feet of the rocket at time T seconds and g(t) is a constant function that represents the height of a platform what situation can be described by (f+g)(t) include a descrption of the domain of (f+g)(t)
The situation described by the function (f+g)(t) would be the total height of the rocket at time t, taking into account both the height it has reached (f(t)) and the constant height of the platform (g(t)).
The domain of (f+g)(t) would be all real numbers, as the function represents the total height of the rocket at any given time t, including both positive and negative values of t. This allows for the calculation of the total height of the rocket at any point in time, regardless of its direction of movement.
