(a)
ToFind : A quadratic function that models the distance of
The required function is
Given information :
The measurements of the distance travelled by an object that is increasing its speed at a constant rate is being taken. The distance travelled as a function of time can be modeled by a quadratic function.
Explanation :
Let
Make table
Therefore,
(b)
To calculate : The zeros of the function.
The zeros are
Given information :
The measurements of the distance travelled by an object that is increasing its speed at a constant rate is being taken. The distance travelled as a function of time can be modeled by a quadratic function.
Explanation :
The quadratic model for distance is
Equate it to zero to find the zeros.
Therefore, the zeros are
(c)
To explain : The representation made by each zero in real world.
The zeros represents the distance travelled at initial time and the distance travelled at negative rate.
Given information :
The measurements of the distance travelled by an object that is increasing its speed at a constant rate is being taken. The distance travelled as a function of time can be modeled by a quadratic function.
Explanation :
The quadratic model for distance is
