Answer:
Hence, the cubic polynomial has:
1 real zero and 2 complex zeros.
Step-by-step explanation:
Clearly from the graph of the function we could observe that the graph passes through the point x=4 i.e. the point (4,0) that means x=4 is a zero of the polynomial.
other than this the graph does not pass through any other point on the real axis.
Hence, the cubic polynomial has only one real zero.
( which is x=4)
Also we know that a cubic polynomial has 3 zeros as one of the zero is real and there are no other real zeros.
That means the cubic polynomial has 2 complex zeros.
Hence, the cubic polynomial has:
1 real zero and 2 complex zeros.
