Question from Carl:
The question on the test has one slight variation from the book:
f (x) = x if -1< x<1the text book showsf (x) = x if -1< x<1
Please clarify if the teacher syllabus is incorrect. We’re finding it is not possible to be both (0,1) and (1,1)…thus only (0,1) is solid and (1,1) is open on the graph.
Answer from Dr. Callahan:
Good catch – you are correct – cannot be both. The question should say
f (x) = x if -1< x<1
