True or False question about finding roots in a function?

The function f ( x ) = -2x^3 + 3x^2 + x + 3 has 5 roots.


True or False?True or False question about finding roots in a function?
either 5 or 6


idk i m just learning about these in mathTrue or False question about finding roots in a function?
False





Fundamental Theorem of Algebra is that a polynomial of n^th degree has a total of n-roots, including duplicate and complex roots
The given function has 3 as its highest power


So the maximum number of roots it can have is 3





So the answer is False
False.


This is a third degree equation. Maximum power of x is 3.


It will have at most 3 roots.
false coz its highest power is 3 and not 5
