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.
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 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?
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.
