You can put this solution on YOUR website!
h(x) = (8x^3)/(5x^2+7)}}} what does -h(x) = ?
-----
A quotient has 3 signs: the numerator, the denominator, and the fraction.
---
To form the negative of a quotient change one of its signs or all three of its
signs.

Your problem
-h(x) = -[(8x^3)/(5x^2+7)]
