Concept explainers
To find: The number of positive real zeros, negative real zeros and imaginary zeros for the give function.
Answer to Problem 54PPS
There are no positive real zeros, 1 negative real zero and 2 imaginary zeros.
Explanation of Solution
Given:
The given graph is as follows.
Calculation:
The polynomial function has degree 3, so it has 3 zeros.
The graph intersects the x-axis once, it means the function has one real zero and because the intersection is on the negative side of x-axis so, the real zero is negative.
The other two zeros are imaginary.
Therefore, there are no positive real zeros, 1 negative real zero and 2 imaginary zeros.
