SOLUTION: 1. Is H(x) = 2x+1/x^2-9 a polynomial function and if so how 2. how do i find each zero and state the multiplicity of f(x)=x(x-1)^2(2x+1)(x+4)^3 please explain so lost 3.how do i

Question 515506: 1. Is H(x) = 2x+1/x^2-9 a polynomial function and if so how
2. how do i find each zero and state the multiplicity of f(x)=x(x-1)^2(2x+1)(x+4)^3 please explain so lost
3.how do i find the polynomial function of degree 3 with the given zeros x=2,-1,1
so sorry and one more f(x)=x+1 and g(x)= x^2-3x-4 find each of the following in simplified form
a. (f+g)(x) b. g/f (x)

1. Is H(x) = 2x+1/x^2-9 a polynomial function and if so how
No it is a rational function.
That means it is a ratio of two functions.

2. how do i find each zero and state the multiplicity of
f(x)=x(x-1)^2(2x+1)(x+4)^3 please explain so lost

Answer the question, "What values of "x" will make f(x) = 0.
Ans: x = 0 ; multiplicity 1
x = 1 ; multiplicity 2
x = -1/2 ; mult 1
x = -4 ; mult 3
----------------------------------
3.how do i find the polynomial function of degree 3 with the
given zeros x=2,-1,1
f(x) = (x-2)(x+1)(x-
--------------------------------
And one more: f(x)=x+1 and g(x)= x^2-3x-4 find each of the following in simplified form
a. (f+g)(x) = f(x) + g(x) = x+1 + x^2-3x-4 = x^2-2x -3
------
b. g/f (x) = (x+1)/(x^2-3x-4)
