To find: The appropriate words to fill in the blanks.

Answer to Problem 3E
Zeros, undefined values.
Explanation of Solution
Given information:
A statement is given as -
"The key numbers for a rational expression are its ______ and its ________"
Calculation:
A rational expression has two types of key numbers − zeros and undefined values.
Zeros are the values of
The values of
A rational expression changes its signs at its zeros and its unidentified values.
A test value is taken from each interval and corresponding value of inequality is calculated (whether positive or negative). The inequality maintains same sign for whole interval.
Hence, appropriate words to fill in the blank would be −
Zeros,undefined values.
