Answer:

A. 2 < t < 4

Step-by-step explanation:

The position of the particle is given to be:

y = t³ − 6t² + 9t

The velocity of the particle is:

dy/dt = 3t² − 12t + 9

The acceleration of the particle is:

d²y/dt² = 6t − 12

Find when the acceleration is 0:

0 = 6t − 12

t = 2

In the interval 0 < t < 2, the acceleration is negative (the particle's velocity is decreasing).

In the interval 2 < t < 4, the acceleration is positive (the particle's velocity is increasing).

The equation which represents the data in the table as in the task content is; Choice C; y = 2x +3.

<h3>What is the equation which represents the data in the table as attached?</h3>

It follows from the task content that the slope of the relation can be determined by means of the slope formula for a linear equation as follows;

Slope = (1-(-1))/(-1 -(-2))

Slope = 2.

Hence, the equation which represents the function is;

2 = (y-(-1))/(x -(-2))

2x + 4 = y +1

y = 2x + 3.

Therefore, the equation which represents the data in the table as in the task content is; Choice C; y = 2x +3.
