Find the real zeros of the function f(x) = -(x+1)^3(x-2)^2 and
their corresponding multiplicities. Use the information along with
a sign chart (diagram) and then the end behavior to provide a rough
sketch of the graph of the polynomial.
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?
For the function
a) f(x)=x^3-9x^2+23x-15
b)f(x)=(x+3)^2(2x+1)(x-1)
c)f(x)=-(x^2-6x+9)(x^2-x-6)
Find:
1) the zeros
2) the y-intercept
3) left-right end behavior
4) the sketch of the graph
use the Rational Zeros Theorem to find all the real zeros of
each polynomial function given below: f(X)=3X^3 + 6X^2 -15X -
30
f(X) = 2X^4 - X^3 - 5X^2 + 2X + 2
Find all zeros and fully factor the function
f(x)=6x^4−19x^3−53x^2+150x−72. Use integers and fractions for
answers, not decimals.
The zeros are
The fully factored form is f(x)=
Consider the function. f(x) = x^2 − 1, x ≥ 1
(a) Find the inverse function of f.
f ^−1(x) =
(b) Graph f and f ^−1 on the same set of coordinate axes.
(c) Describe the relationship between the graphs. The graphs of
f and f^−1 are reflections of each other across the line ____answer

(d) State the domain and range of f and f^−1. (Enter your
answers using interval notation.)

If f is a polynomial of degree 3 or more how would you
use real zeros of f to determine the open intervals over
which f(x) > 0 or f(x) < 0. How and where does the sign of
f change.
