Answer: There are 7 roots for the polynomial function.
Explanation:
Since we have given that
![f(x)=8x^7-x^5+x^3+6](https://img.qammunity.org/2020/formulas/mathematics/middle-school/qhrz9qqr3hm0o8uy7lm3dpwn212s3iqx7y.png)
We need to find the number of roots exist for the polynomial.
As we know that
Number of roots = Highest degree of the polynomial.
So, the number of roots = 7
Hence, there are 7 roots for the polynomial function.
