ANSWER
The root at point P may be
![(3)/(5)](https://img.qammunity.org/2020/formulas/mathematics/high-school/ham59d8d32yipgtxeagz7evpc6d3yqvvcb.png)
Step-by-step explanation
The given function is
![f(x) = 5 {x}^(5) + (16)/(5) x - 3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/6sr3t8dhffdl4iqleqh9e6fgyv6xsnxtpi.png)
The potential rational roots are all factors of -3 expressed over all factors of 5.
These are:
![\pm (1)/(5) , \pm (3)/(5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/g7j1612tij8r90vui2rsuagrjq8njmq906.png)
Since the root of f(x) at P is closer to 1 that zero and it is positive , that potential may be
