There are two parts to this answer - skill and understanding. You need to have good elementary algebra, trigonometry, and coordinate geometry skills at the very least. That is, you need to be able to solve for variables and perform the necessary manipulations on terms (rational exponents in particular). You need to be able to use the trig functions and use some basic identities. You need to be able to work in a two dimensional Cartesian coordinate system (lines, slopes, curves, distance, etc…). You should understand concepts such as the difference between a root and a zero of a function, how a function is defined and why, how functions are classified (algebraic, polynomial, rational, etc…), and the logic behind the general algebraic manipulations (why distributivity is valid, why a negative exponent denotes the multiplicative inverse with the denominator to the positive exponent, etc…), to name a few. This is the bare minimum I come up with during my first go at it. Given more thought there would probably be other things I deem essential and it’s a fine line anyway. That is, an individual with better understanding but less skill will have a better chance of filling in their gaps as t go as opposed to the individual with more skill and less fundamental grasp on the material. The most comprehensive (to truely be prepared with a foundation to build on), but minimalistic (what you put in is what you get out, it’s not oversimplified so you really need to work the material) is Basic Mathematics by Serge Lang. If I were to answer your question with a list, it would be his chapter and section headings.
