2.06 Unit lest: Derivatives - Part 2 Pool 1 Question 1 (3 points) For f(x ) : (X-1' -, use the definition of differentiability f' (x) = lim f(xth)-f(x) h- 0 h - to determine if f(x) is differentiable at x = 1. A/ Question 2 (3 points) For f(x) =[x - 1|, use the definition of differentiability fi (c ) = lim f(ctax)=f(c)+ Ax determine if f(x) is differentiable at c = 1. 4x-0
