Answer: 3 zeroes.


Explanation:-

  • The fundamental theorem of algebra states that any polynomial with degree m>0 and complex coefficients has atleast one complex root.
  • Corollary of fundamental theorem states that for any polynomial with degree m>0 has exactly m solutions.

The given function is
f(x)=4x^3-x^2-2x+1

Because it is a polynomial function with degree 3>0 , Therefore by corollary of fundamental theorem of algebra , it has 3 zeroes.
