. . x. 2 S x S 1 Graph the followmg function: f (x) = 2 x, 1-: x g 3 a. Explain why the function is continuous at x = l. b. Show that the function is not differentiable at x = l in two different ways. First, give an informal explanation based on the graph of the function Second, use the alternate version of the definition of the derivative f '(x0]= lim Maud one-sided limits to give a formal reason that the x1n'u I. _ x0 derivative fails to exist at x = l
