Sketch the graph and show all local extrema and inflection points. Do not use technology. Use formal notation to justify where extrema are located and where inflection points are located.\\ 20) $y = \left(x-\frac{x}{2}-5\right)^4$\ Use l'Hopital's Rule to evaluate the limit.\ 21) $\lim_{\theta \to 0} \frac{5-5\cos\theta}{\sin^2\theta}$

Step 1
Sketch the graph: Since we don't have any specific function given, we cannot sketch the graph without more information. We need to know the equation of the function to plot it on a graph. Show more…

Find the first and second derivative and then use the SDT to determine any points of inflection and intervals of concavity. Be careful of domain. Be sure to include your sign graph. Also write any inflection points as ordered pairs. (20 points)
