Concept explainers
Find the real zeroes of the function to the nearest tenth.
Answer to Problem 43SGA
Explanation of Solution
Given information:
Calculation:
Here, we have:
Now, we can see that there are three complex zeros for this function.
We will use table feature on a graphing calculator to solve this.
Now, use
Now, check for some more zeroes:
Thus, the zeroes are between
Now, use
As,
As,
As,
Hence, the zeroes are about
