Hi Sharon, For sequence questions, the "n" stands for the term you are finding, so if you are looking for the first term, replace "n" with "1" in the equation and solve. If you are looking for the second term, replace "n" with "2" in the equation and solve. And so on, and so on...
Integers are real numbers, but many rational numbers are NOT integers. For example, 5/1 can be written as 5, so 5/1 is an integer. But 2/3, while it is a rational number (it can be written as a ratio, or fraction), 2/3 is NOT an integer.
Hi Mrs. Kerr...i really dont understand how to do 1.8 that well. on the review, it said that I sub n= 12/n....how do we solve that for the first four sequences and the 98th sequence??? thanks! i hope we can review that before the test....
in 1.8, if a question stated that A(sub)11 equals 22.83 and it asked what A(sub)3 was then how do i figure that out? Do i divide?
ReplyDeleteI know this is from a long time ago but i would still like to review domain and range off a graph. how do we do it? Can we review during class?
ReplyDeletefor 1.4, what are some integers that are not real numbers? what are some integers that are not rational numbers?
ReplyDeletewhat do you do if the problem shows a graph, then shows a variable with a number in parenthesis? For example, x(7.5)-y(5.5)
ReplyDeleteNo questions so far...

Hi Kosta,
ReplyDeleteWhen you have a function f(x) = .... , and then you are given f(4.5), replace every variable in the equation with 4.5 and solve.
