Exercise 1 Page 499

Just like with fractions, we cannot divide by 0 in rational functions.

x=0

Practice makes perfect
Consider the given rational function.

y=5/x To identify the excluded value, we must remember that the denominator cannot be 0 because division by 0 is not defined. In this case, if x=0, the value of the denominator is 0. Therefore, the excluded value is 0.
