Unformatted text preview: GROUP WORK 4, SECTION 3.3 Sparse Data Assume that f (x) and g (x) are differentiable functions about which we know very little. In fact, assume that all we know about these functions is the following table of data: l-l----ll This isn’t a lot of information. For example, we can’t compute f’ (3) with any degree of accuracy. But we are still able to ﬁgure some things out, using the rules of differentiation. l. Leth (x) = (35% f(x). What is h’ (0)? 2. Let] (x) = —4f (x)g(x). What is j’ (1)? xf (x) g (x) 3. Let k (x) = . What is k’ (—2)? 4. Let 1 (x) = x3 g (x). Ifl’ (2) = —48, what is g’ (2)? 5. Letm (x) = %. What is m’ (l)? ...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
