4502 @Anz) f(z-6) + 6 Question 15 (multiple choice) A car decelerates at a constant rate as it approaches a red light. The velocity of the car in time in seconds. After five seconds, the car reaches a complete stop. 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(z) +20. wh ere z is Which situation is appropriately modeled by reflecting f(z) across the s-axis? O The car begins to drive in reverse O The car remains stopped. O The car immediately begins to accelerate at twice the same rate it had previously decelerated O The car immediately begins to accelerate at the same rate it had previously decelerated level. the rocket

Explanation / Answer

Answer: Car remains stopped (As shown below)

f(x) = - 4x + 20

Velocity of the car at t = 0 seconds:

f(0) = - 4(0) + 20 = 0 + 20 = 20 m/s

Velocity of the car at t = 5 seconds:

f(0) = - 4(5) + 20 = 0 = 0 m/s

Car comes to a halt in 5 seconds.
