Need what is the average rate of change of the function over the interval x = 0 to x = 8? f (x)=2x+3/3x−3
Answers: 1
![\bf \cfrac{\left[ \frac{2(8)+3}{3(8)-3} \right]~~-~~\left[ \frac{2(0)+3}{3(0)-3} \right]}{8}\implies \cfrac{\left[ \frac{19}{21} \right]~~-~~\left[ \frac{3}{-3} \right]}{8} \\\\\\ \cfrac{\frac{19}{21}-(-1)}{8}\implies \cfrac{\frac{19}{21}+1}{8}\implies \cfrac{\frac{40}{21}}{\quad 8\quad }\implies \cfrac{\frac{40}{21}}{\quad \frac{8}{1}\quad }\implies \cfrac{40}{21}\cdot \cfrac{1}{8} \\\\\\ \cfrac{5}{21}\cdot \cfrac{1}{1}\implies \cfrac{5}{21}](/tpl/images/0119/6365/dcbf8.png)
