The distance traveled by a toy car can be modeled by D(t) = t3 − 3t2 + t − 3, where t > 3 represents time in seconds. If the
car traveled for t − 3 seconds, identify the expression that represents the speed of the toy car.
1 answer:
Answer:

Step-by-step explanation:
We are given that
Distance traveled by a toy car

Where t>3
Time taken by car =t-3 seconds
We have to find the expression which represents the speed of the toy car.
We know that

Using the formula




Hence, the expression which represents the speed of the toy car
