"if f(x)=x+1/x then the set of values for which f increases is"

Anettt [7]

The solution for this problem would be:
f'(x) = 1 - 1/x^2 = (x^2 - 1)/x^2
is positive where |x| > 1
hence (-inf, -1) and (1, inf) are the regions in which f' is positive and therefore f is increasing.
Therefore, the answer is (-infinity,-1] U [1,infinity).

Korey is planning to open a comic book store. He has developed the following expense breakdown for set-up and operation for the

pentagon [3]

The total amount of cash money that Korey have is the summation of his savings and his inheritance which is equal to Korey cash = $8500 + $25,000.
To identify the amount needed to be funded by loans or investors, we need to know first the total of expenses plus set-up plus operation expenses and other expenses to operate the bookstore subtracted by his savings.

Thus, let "AL" be the amount needed through loans while letting "TE" for total expenses.

AL=TE-($8500+$25000)
AL=TE-$33,500

This is the equation needed to determine the amount needed.
