Question

a cubic polynomial can have how many zeroes ?​

Answer 1

Answer:

Since this graph is continuous, in between these values there must be at least one real zero (ie the graph must cross the x-axis at least once to go from positive to negative and vice versa). So this shows that any cubic polynomial (actually any polynomial of odd degree) will have at least one real zero.

Hope it helps you :)

Answer 2

Q . a cubic polynomial can have how many zeroes ?

three zeros

Regardless of odd or even, any polynomial of positive order can have a maximum number of zeros equal to its order. For example, a cubic function can have as many as three zeros, but no more.
