Answer to Problem 35CR
Excluded value:
Explanation of Solution
Given:
The function:
Concept Used:
Rational expression is in the form
Excluded values are also called points of discontinuity. These are the values that make the denominator equal to zero and are not part of the domain.
In any rational function, the denominator cannot be zero.
To find the excluded value of the function, make denominator equal to zero and simplify.
Calculation:
In any rational function, the denominator cannot be zero.
So we can write the excluded value:
Excluded value
Thus, excluded value:
