Question 1013835: 4.2
Find the zeros for the given polynomial function and give the multiplicity for each zero. State whether
the graph crosses the x-axis and turns around at each zero.
f(x)=x^3 -6x^2 +9x
a. The zeros are:
b. The multiplicity at the leftmost zero is:
(type a whole number)
c. The multiplicity at the rightmost zero is:
(type a whole number)
d. Determine whether the graph crosses the x-axis or touches the x-axis and turns around at the leftmost zero
e. Determine whether the graph crosses the x-axis or touches the x-axis and turns around at the rightmost zero
My answers:
a. 0,3
b.0
c.3
d.crosses the x-axis
e.crosses the x-axis
answers:
a. 0,3 -> correct
b.0 -> correct
c.3-> incorrect:factored form of given equation is ;so,the multiplicity at the rightmost zero is (you have two times in factored form)
d.at the leftmost zero the graph the x-axis-> correct
e.at the leftmost zero the graph the x-axis-> incorrect
at the leftmost zero the graph the x-axis and turns around at the rightmost zero
