Acar decelerates at a constant rate as it approaches a red light. the velocity of the car in meters per second as it decelerates is modeled by the function f(x)=−4x+20, where x is time in seconds. after five seconds, the car reaches a complete stop. which situation is appropriately modeled by reflecting f(x) across the x-axis? the car immediately begins to accelerate at twice the same rate it had previously decelerated. the car begins to drive in reverse. the car immediately begins to accelerate at the same rate it had previously decelerated. the car remains stopped.
