Q. What is the value of \newlinef(9)f(9) for the function \newlinef(x)=32+16+xf(x)=32+\sqrt{16+x}?\newlineA. 32+732+\sqrt{7}\newlineB. 32+1932+\sqrt{19}\newlineC. 3737\newlineD. 3939
  1. Calculate value inside square root: Calculate the value inside the square root for f(9)f(9).f(9) = 32 + \sqrt{16 + 9}\= 32 + \sqrt{25}
  2. Simplify square root and add: Simplify the square root and add to 3232.\newline25=5\sqrt{25} = 5\newlinef(9)=32+5f(9) = 32 + 5\newline =37= 37
