Domain in context Determine an appropriate domain of each function. Identify the independent and dependent variables. 21. A stone is thrown vertically upward from the ground at a speed of 40 m/s at time t = 0. Its distance d (in meters) above the ground (neglecting air resistance) is approximated by the function f ( t ) = 40 t − 5 t 2 .
