Answer:
9. The range of the function $f(x)=\frac {4x^{2}-3x+4}{2x^{2}-8}$ is all real numbers except $-2$.
To find the range, we need to determine the values of x for which the function is undefined. In this case, the function is undefined when the denominator is equal to zero, i.e., $2x^{2}-8=0$. Solving this equation, we get $x=\pm2$. Since the function is undefined when $x=-2$, the range of the function is all real numbers except $-2$.
10. The range of the function $f(x)=\frac {3x+4}{2x^{2}-8}$ is all real numbers except $x=2$.
