Find the domain of the function. \( f(x)=\log _{4}\left(\frac{x+9}{x}\right) \) The domain is \( \square \). (Type your answer in interval notation.)

30. List the first five terms of the sequence defined recursively by \( a_{n}=\frac{a_{n-1}}{2}+2 ; a_{1}=68 \)

Julie swam, biked, and ran in a 22.2 mile triathlon. She completed the race in 2.15 hours. The function \( m=13.8 \mathrm{~h} \) represents the miles \( m \) Julie biked in \( h \) hours. Was her average speed biking less than or greater than her average speed for the entire race? Justify your answer. Round to the nearest tenth if necessary.

Find the domain and range of \( y=\log _{2}(8-4 x) \).

Which of the following is equivalent to \( \log \left(\frac{1}{x y}\right) \) ? (1 point) \( 1-\log x-\log y \) \( \log x-\log y \) \( -\log x-\log y \) \( -\log x+\log y \)

Enter the appropriate value to answer the question or 16. Graph the function \( f(x)=\sqrt{x+2}-5 \)
