a.
Find the interval
a.
Answer to Problem 88E
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 square of a number never be negative hence no key points
Hence, the solution set is,
b.
Write a conjecture about the interval
