Question

Asked Oct 15, 2019

I need help with question 29 in Section 3.6, page 223, of the *James Stewart Calculus Eighth Edition *textbook.

Step 1

- Recall d[ln(x)] / dx = 1/x
- Recall the chain rule of differentiation

Step 2

Please see the white board. The expression for f'(x) is the derivative.

Step 3

ln(x) is defined for x>0. Log of a negative number is not defined.

Hence, ln(x2 – 2x) is ...
