The values of
Explanation of Solution
Given Information:
The functions
Explanation:
Substitute
By using substitution
Find factors of the quadratic equation,
Now resubstitute values of
But square of the term cannot be negative, so
Taking square root on both sides,
If
The points

Answer to Problem 27AYU
Solution:
The domain of
Explanation of Solution
Given Information:
Explanation:
The domain of the function is set of all values of
Since it is a rational function, it is defined for all values of
Set denominator of the above function to 0,
But square of the term cannot be negative. So this is not possible.
Thus, domain of the function
