use the given zero to find the remaining zeros of each
polynomial function
23. f(x)=x^3-4x^2+4x-16; zero; 2i
27. x^4-9x^3+21x^2+21x-130; zero: 3-2i
Find the complex zeroes of each polynomial function. Write f in
factored form.
35. f(x)=x^4+5x^2+4
I tried using Descarte's rule for questions 23 and 27, but I
don't what to do after that. Also, after you explain the steps I
need to solve the question, could you help understand why these
steps are necessary?
1. For the function P(x) = 4x^2 - 16 / x^2 -5x
find the
a) List X Intercept(s) if any
b) List Y Intercept(s) if any
c) List Horizontal Asymptote(s) if any
d) List Vertical Asymptote(s) if any
e) Domain

Question 5
Find all solutions of this system.
4x + 2y + 3z = 0 3x y + 2z = 0 x + 2y − z = 0
Compare the value of the determinant of the coefficient matrix
to zero using the nature of the solution.
