Evaluate \frac{d^{2} y}{{d x}^{2}} when x = \ln 2 and y = 2 .

y = f (x)

\frac{d y}{d x} = f^{'} (x)

\frac{d^{2} y}{{d x}^{2}} = f^{″} (x)

if y = 2 \Leftrightarrow f (x) = 2 \Rightarrow f (\ln 2) = 2

f (x) = 2 \Rightarrow f^{'} (x) = 0 \Rightarrow f^{″} (x) = 0 \Leftrightarrow \frac{d^{2} y}{{d x}^{2}} = 0
