The causes of back pain are nearly as numerous as terms used to describe the symptoms. Back pain is a primary reason people seek medical attention. Considering that almost 80% of the adult population will encounter some form of back pain, it could be said that back pain is a universal epidemic.
Multiplicity of a root of a polynomial[edit] Let F be a field and p(x) be a polynomial in one variable and coefficients in F. An element a â F is called a root of multiplicity k of p(x) if there is a polynomial s(x) such that s(a) â  0 and p(x) = (x â a)s(x).
From Renee: I am looking to find the domain of a derivative of a radical function, one such as: f(x) = the square root of (8 â x). I am kind of unclear on how domains work for derivative. I don't understand how you take a function's domain and use that to find the derivative's domain.rom Saher: Discuss domain of the function, f(x)= (x+1)(x-2) / (x+3), with the entire thing under a square root. I'm being taught how to find the domain using the number line.
