Section 1.7
Questions 32, 34, 36, 38.

See attachment.

Note: Only part (d) will be posted.

32d. If f(x) = [[ x ]], then g(x) = -f(x) + 1.

34d. If f(x) = | x |, then g(x) = |(1/2) • f(x)|.

36d. If f(x) = x^2, then g(x) = (1/2)• f(x) - 2.

38d. If f(x) = | x + 1 |, then g(x) = -2• f(x) - 3.

Section 1.7 was a good ride.

Question:

How do I keep myself from forgetting the early chapters when several chapters ahead in my self-study?

 

[MathLover1]

You do forget things you are not working on. So, to keep yourself from forgetting the early chapters, you need to work on it. Memory must be trained.

I know that memory must be trained. Are you saying that I should revisit the early chapters from time to time? Helping students with homework is a good way to help keep the early chapters in tune. I can't do that here. This site is dead. Any suggestions?

 

[MathLover1]

yes, revisit the early chapters from time to time, read formulas, definitions, rules

I guess revisiting the early chapters is a solution to the memory issue. In your case, how do you remember Calculus l, ll, and lll? You have not answered, to my knowledge, any calculus questions lately. Right?

I am answering a lot of calculus questions on algebra.com

my major is math, so I did a lot of Calculus l, ll, and lll and more like

An amazing journey for sure. Congratulations!
