1. From the graph of f, state each xvalue at which f is discontinuous. Explain why the function is discontinuous at that point. For each x-value, determine whetherf is continuous from the left, from the right, or neither 2. Evaluate the limit, if it exists. Show your work. 1' 2x2x+7 x112 4x2+5x6 3. Find the following limits using the graph of h(x). 10 -10 -5 0 - 5 a. lim h(x) x--2- e. lim h(x) x-3+ b. lim h(x) f. lim h(x) X -3 c. lim h(x) x- -2 g. lim h(x) x-00 lim h(x) x-3- 4. Determine if the function f (x) is continuous at x = 4. Explain your choice in complete sentences using the definition of continuity. x2 - 16 f ( x ) = x - 4 if x * 4 if x = 4
