# MCS-236: daily assignment

- Read sections in appendix A on FUNCTIONS (pages 483-485).
- Let A = {a,b,c} and let B = {b,c,d,e}. How many functions are there
mapping A to B ?

- Finish section 1.1,
*What is a graph?* through page 14.
- As always, take out a piece of paper and draw a small
example of each definition. As with example 1.1.3,
whenever possible, compare an example reflecting the formal
definition with a drawing.

- You should now be prepared to attack the homework. Try solving
some of the problems.
- Please come prepared with questions each day!
