f(x)=2x^3-3x^2+3x-2
How many zero's does it have, How many real zeros and what are the real solutions? (This is just an Example on my paper)

1st derivative test?

anonymous · Answer

Yes

goten77 · Answer

well that wont help much but the general rule is whatever power its to is how many zeroes it will have -1

anonymous · Answer

It asks for the total number of zeros 
Then asks the number of real zeros

anonymous · Answer

It says Function has _____ total zeros 
and Function has ______ real zeros.

goten77 · Answer

k so what ied do is 1st factor and get
(x-1)(2x^2 -x+2)
then set that = to 0

anonymous · Answer

& Solve for X ?

goten77 · Answer

yes...well its obvious x=1 is the 1st zero since x-1=0 x=1
now the 2nd 1 is the quadratic part

anonymous · Answer

Oh okay . Ty (:
