Question from Morgan, a student: Use the derivative rules to differentiate each of the following: |
Hi Morgan,
For the first problem, $f(x) = \large \frac{1}{x - 1}$ I would suggest the quotient rule and remember that $f^{\prime}(1) = 0.$
For the second problem write $\sqrt {x} \mbox{ as } x^{1/2}$ and use the power rule.
