Answer:

odd

Explanation:

An odd function has the characteristics ...

  • symmetrical about the origin
  • f(-x) = -f(x)

An even function has the characteristics ...

  • symmetrical about the y-axis
  • f(-x) = f(x)

__

The graph of the function shows symmetry about the origin. If we substitute -x for x, we get ...


h(-x)=(3(-x)^3)/(8(-x)^2-9)=(-3x^3)/(8x^2-9)\\\\h(-x)=-(3x^3)/(8x^2-9)=-h(x)\qquad\text{the function is odd}

_____

Additional comment

Both the numerator and denominator are polynomial functions. A polynomial function is odd if it contains only odd-degree terms, like the function in the numerator. A polynomial function is even if it contains only even-degree terms, like the function in the denominator. (A constant is 0 degree--even.)

A rational function consisting of the ratio of odd or even functions (not "neither"), will be odd or even according to the parity of the ratio:

odd/odd = even/even = even function

odd/even = even/odd = odd function . . . . . the situation in this problem
