The rate of change of the function described in the table is:
![\dfrac{2}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D)
<h2>
Step-by-step explanation:</h2>
We know that the rate of the change is the ratio of the change in the y-values to the change in the x-values.
The table of values are as follows:
x y
-1 1/10
0 1/2
1 5/2
2 25/2
3 125/2
The rate of change is calculated as follows:
![\text{Rate\ of\ change}=\dfrac{\dfrac{1}{2}-\dfrac{1}{10}}{0-(-1)}\\\\\text{Rate\ of\ change}=\dfrac{\dfrac{5-1}{10}}{1}\\\\\text{Rate\ of\ change}=\dfrac{4}{10}\\\\\text{Rate\ of\ change}=\dfrac{2}{5}](https://tex.z-dn.net/?f=%5Ctext%7BRate%5C%20of%5C%20change%7D%3D%5Cdfrac%7B%5Cdfrac%7B1%7D%7B2%7D-%5Cdfrac%7B1%7D%7B10%7D%7D%7B0-%28-1%29%7D%5C%5C%5C%5C%5Ctext%7BRate%5C%20of%5C%20change%7D%3D%5Cdfrac%7B%5Cdfrac%7B5-1%7D%7B10%7D%7D%7B1%7D%5C%5C%5C%5C%5Ctext%7BRate%5C%20of%5C%20change%7D%3D%5Cdfrac%7B4%7D%7B10%7D%5C%5C%5C%5C%5Ctext%7BRate%5C%20of%5C%20change%7D%3D%5Cdfrac%7B2%7D%7B5%7D)
