    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?

    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?

    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
