10. Recall that at the beginning of the semester we spoke about how to tell whether a given graph in rectangular coordinates represents a function. (a) Given a graph in rectangular coordinates, how do we tell whether the graph represents a function? (b) Given a graph in polar coordinates, how might we tell whether the graph represents a function? (c) Using a graphing calculator or Desmos, graph r(0) = 3cos(2.10). Does this graph represent a function? Justify your answer.
