I do not understand this problem nor how to solve it. It looks like an inequality but I do not see how to solve it.

What are the vertical asymptotes of the function f(x) =5x+5/x2 + x-2

Asequence {an} is defined recursively, with a1 = 1, a2 = 2 and, for n > 2, an = an-1 an-2 . find the term a241

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
