#1**+1 **

f(x) = -3 / [5x^3]

Note that x cannot be 0 because it will make the denominator 0

Also.....the range willl be the same....all y except y = 0

To see this....set the left side = 0

0 = -3 / [ 5x^3] multiply both sides by 5x^3

0 * 5x^3 = - 3

0 = -3 this says that there is no x value that makes y = 0

So...the domain and range is (- inf, 0 ) U (0, inf)
