You take measurements of the distance traveled by an object that is increasing its speed at a constant rate. The distance traveled d as a function of time t can be modeled by a quadratic function. What is the quadratic function that models distances of 21 ft at 1 s, 59 ft at 2 s, and 141 ft at 4 s?

Follows are the solution to this question:

Step-by-step explanation:

Given:

All points are on the graph including its quadratic function, in order to install their coordinates to values of x and y with the following values:

     Inserting the coordinates of the first point

             Inserting the coordinates of the second point

      Inserting the coordinates of the third point

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
