To discuss the differentiability of the function \( f(x) = |\log_e x| \) for \( x > 0 \), we can follow these steps: ### Step 1: Understand the Function The function \( f(x) = |\log_e x| \) involves the natural logarithm of \( x \) and the absolute value. The natural logarithm, \( \log_e x \), is defined for \( x > 0 \) and has specific behavior: - \( \log_e x < 0 \) when \( 0 < x < 1 \) - \( \log_e x = 0 \) when \( x = 1 \) - \( \log_e x > 0 \) when \( x > 1 \) ...
