3) Find the zeros of the polynomial function and state the multiplicity.
f(x) = x³ + 4x² 9x - 36
4) Graph the polynomial function. Don't forget to find the x-intercepts to divide the x-axis
into intervals and choose a test point for each interval, y — intercept.
f(x) =
5) Use long division to find the quotient Q(x) and remainder R(x).
P(x)
6x³ 2x² + 4x 1 and d(x) = x - 3
6) Find a polynomial function of degree 3 with the given numbers as zeros:
1 √2, 1 + √2
=
1
1
a) f(x) = -¹/5
= - x² + 2x³
7) Find a polynomial function with rational coefficients where some of its zeros are
a)-i, 6
b) -1, 4, 1 + i
8) Graph the function. Be sure to label all the asymptotes. List the domain and the x and y
intercepts.
b) f(x) =
x² + 3x
2x3-5x²-3x
