a.
Answer to Problem 87E
Explanation of Solution
Given information:
Find the interval
Calculation:
Consider the equation
Now, Find the interval
The standard form of equation is,
For at least one real solution discriminant must be greater than or equal to zero,
So, the key numbers are
Now create the test interval using the domain as shown,
Hence, the solution set is,
