(b) On what interval is f constant? (c) Sketch a graph of f . Is f continuous on its domain? (d) Find the xvalue(s) where f ( x ) = 2 . Problem #2. Let g ( x ) =  2 x 6 if 8 x  2 x if 2 < x < 2 1 2 x + 1 if 2 x 8 . (a) Evaluate g at x = 8 , 2 , 2 , and 8 . (b) For what xvalues does g ( x ) have a positive slope? (c) Sketch a graph of g . Is g continuous on its domain? (d) Find the xvalue(s) where g ( x ) = 0 . Problem #3. Let h ( x ) =  2 if x < 2 if 2 x < 3 x if x 4 . (a) Determine the domain of f . (b) Evaluate f ( 2) ,f (0) , and f (3) . (c) Graph f . (d) Is f continuous on its domain? Problem #4. Let f ( x ) = 3 if 4 x  1 x 2 if 1 < x 2 1 2 x if 2 < x ....
