Concept explainers
To find: The number of positive real zeros, negative real zeros and imaginary zeros for the give function.
Answer to Problem 55PPS
There is 1 positive real zero, 2 negative real zeros and 2 imaginary zeros.
Explanation of Solution
Given:
The given graph is as follows.
Calculation:
The degree given is 5 its means there are 5 zeros in the graph. As shown in the graph, the graph intersects x-axis 3 times, meaning there are 3 real zeros.
Furthermore, the 3 real zeros, showed that 2 of the zeros are negative zeros and the remaining 1 is a positive real zero.
The remaining zeros are complex or imaginary zeros.
Therefore, there is 1 positive real zero, 2 negative real zeros and 2 imaginary zeros.
