Roger was told to think of a number, add 20 , then divide the result by 3 . The answer was Jower than Roger's original number. Deteruine the range of possible numbers Roger may have originally chosen.

a. \( \frac{2 x^{3}+6 x-6}{x^{3}-1} \)

5.7 Determine the equation of \( h \) if \( h(x)=g(x+1)-2 \)

Subtract the polynomials: \( (5x^{3} + 2x^{2} - 7) - (3x^{3} - x^{2} + 4) \)
