The date (in bold) refers to the day the assignment is given, not when it is due.
Doing homework daily (making an honest effort and using anything at your disposal) is the only way to succeed in the course. I will occasionally collect a set of problems, which I will announce ahead of time. Usually, though, a collected assignment is a separate problem I hand out.
Tues-Wed Jan 16-17 Read Sec 1 and Sec 2; problems Ch 1, p 5, #1, 2, 7, 8; problems Ch 2, pp 15-16, #1-13
Study your notes on graph sketches to know.
The math 220 Video page is mainly for calculus. But, if you need to brush up on exponents and radicals, or on domain of a function, check out Math 108 video link. The first couple of links there are for exponents and radicals. Scroll down a little way to find the link for finding domain of a function.
Fri-weekend Jan 19-21 Read Sec 3 and Sec 4; do problems Sec 3, pp 26-27
Go to SUPPLEMENTAL MATERIALS and do Worksheets 3, 4, and 8 (exercise 1 only) for more practice on exponents, domain and composition of functions.
Mon Jan 22 Here are thumbnails of the Essential function sketches. The last several all a little faint. I will repost some day.
Finish Sec 3 problems if you have not done so.
Read Sec 4 again. View these helpful videos:
