Ken goes fishing each weekend and he made a graph of the number of fish he caught in the past five weekends. Which of the following graphs is discrete? A. Graph A B. Graph B C. Both are continuous D. Both are discrete

ANSWER
B. Graph B
EXPLANATION
Graph B is discrete, because there are no values of the functions between each point, you can only know the value of the function for weekends 1, 2, 3, 4 and 5.
On the other hand, graph A is continuous, because there are values for each point on the graph - the points are all connected.
