R.K. Sahi x2 +1, ifx50 1. (15 points) Let the function f be defined by f(x) = 2-x, if0 2. (a) Sketch the graph of f(I). (b) Find the x-value(s) at which f is not continuous. For each suchvalue, say whether f is contin- uous from the left, from the right, or neither. 2. (5 points) Evaluate the following one-sided limits analytically. lim 4 [20] + 2 where [x] is the x -+ 5 - 6+ x greatest integer function
