Yeah…I don’t think a week is going to cut it. Most of this stuff is simply logic…they are more or less simple definition type questions, such as #3, where you should know to plug in g(x) for the values of x in f(x) in order to get f o g(x), which you should know is another way of writing f(g(x)).

Just for fun, here’s #2

a+b=24 because the equation shows it to be linear. Therefore, it has a slope.
Using the first and fourth table entries, the slope is the difference in y divided by the difference in x. This ends up as 6/3, or 2. Now, you can either solve the equation or simply add 2 to y for every 1 you add to x. Doing this to the first point, you get points (3,11) and (4,13). and you find that 11 and 13 are a and b respectively, simply add them.
