Write the expression without negative exponents.
-$$y = - 5 x ^ { - 3 } - x ^ { - 2 } + 2 x ^ { - 1 } + 2 x ^ { 2 } + 4 x$$
A) $y = - \frac { 5 } { x ^ { 3 } } - \frac { 1 } { x ^ { 2 } } + \frac { 2 } { x } + 2 x ^ { 2 } + 4 x$
B) $y = - 5 x ^ { 1 / 3 } - x ^ { 1 / 2 } + 2 x ^ { 2 } + 6 x$
C) $y = - \frac { 5 } { x ^ { 3 } } + \frac { 1 } { x ^ { 2 } } + \frac { 6 } { x }$
D) $y = - \frac { 5 } { x ^ { 3 } } - \frac { 1 } { x ^ { 2 } } + \frac { 2 } { x } + \frac { 2 } { x ^ { 2 } } + \frac { 4 } { x }$

To write the expression without negative exponents, each term with a negative exponent is rewritten as the reciprocal of the term with a positive exponent. For example, $x^{-3}$ becomes $\frac{1}{x^3}$, and so on for each term with a negative exponent in the original expression.
