Devin tried to find the derivative of $ -3 x-11 $ using basic differentiation rules. Here is his work: \[ \begin{aligned} & \frac{d}{d x}(-3 x-11) \\ \text { Step 1 }= & \frac{d}{d x}(-3 x)-\frac{d}{d x} \end{aligned} \] Step $ 1 \quad=\frac{d}{d x}(-3 x)-\frac{d}{d x} $ Step $ 2=\frac{d}{d x}(-3 x)-0 $ Step $ 3 \quad=-3 \frac{d}{d x}(x) $ Step $ 4=-3 \cdot 1 $ Step $ 5=-3 $ At which step did Devin make a mistake, if at all?

• Section 11.9 in the textbook discusses the hydration of internal alkynes through the addition of the first water molecule to the triple bond. The first hydration reaction forms an enol, an alcohol bonded to a vinyl carbon. Enols immediately undergo a special type of isomerization reaction called tautomerization to form carbonyl groups - aldehydes or ketones. Draw the mechanism of the hydration and the enol ketone tautomerization reaction using one of the alkynes in calicheamicin. Use the formal arrow pushing formalism and show the product of this hydration.

(10 pts.) Draw the state diagram for an NFA that accepts binary strings containing two 0's separated by 3k 1's for some $k \ge 0$. (10 pts.) Convert the following e-NFA to an equivalent DFA: (\lambda is another symbol of $\epsilon$, the empty string). You'll need to do two conversions: e-NFA to NFA and then to DFA for this problem.
