is this correct then. Why might fuction notations be important? My answer: a function notation shows how x computes based on an equation. The function of x means the given equation a certain value. Such as f(x)=x + 7. For example f(6)=6 + 7. So, f(6)=13 the function equals 13...

**Binomial**

Help me on this one :( Express y= (7-3x-x^2)/[((1-x)^2)(2+x)] in partial fractions. Hence, prove that if x^3 and higher powers of x may be neglected, then y=(1/8)(28+30x+41x^2) I did the first part of expressing it in partial fractions. (Since it's very difficult to type out ...

**math**

use the rational zero theorem to find all the real zeros of the polynomial function. use the zeros to factor f over the real numbers: f(x)=4x^4+9x^3+30x^2+63x+14 I cant even find sample problems to help me figure this out. help me please?
