how do you find the number of real and imaginary zeros in a function?

To tell the number of imaginary and real zeros of a function, first get the sum number of roots of a function. You can do this by using the corollary to the fundamental theorem of algebra. Then, determine the maximum number of possible real roots by using Descartes' rule of signs. Hope this helps!
