The changing speed of a car is modeled by the function
S(t) = -4t + 35, where t is time in
seconds. Interpret the model.
A The car has an initial speed of
O units and is speeding up to a
speed of 35 units by 4 units per
second.
B The car has an initial speed of
4 units and is speeding up by
35 units per second.
с The car has an initial speed of
35 units and is slowing down
by 4 units per second.
D The car has an initial speed of
35 units and is speeding up by
4 units per second.
