5. From the graphs below determine which graph represent a continuous function Graph 1 or Graph 2 (explain why f(x) Graph 1 Graph 2 6. From Graph 3 a) Does the graph below represent a Piecewise-Defined Function? b) Determine how many pieces the function has and define the intervals. c) Is it true that piece 1 is defined on interval (-es, -1)? d) Is it true that piece 2 is defined on interval [-1, 2)? e) is it true that piece 3 is defined on interval [2, = =)?
