Question

in the given graph of a cubic polynomial, what are the number of real zeros and complex zeros respectively

Answer 1

1 real and 2 complex

Explanation:

The Fundamental theorem of Algebra states that a polynomial of degree n has n zeros, some may be complex.

A cubic is a polynomial of degree 3 , then has 3 zeros.

From the graph

There is a real zero at x = 4

Thus the other 2 must be complex
