Question

Can somebody help me with the question posted in the comments?

Answer 1

I'm not sure what the answer is. :(

Answer 2

What are excluded values? Do you know what they refer to there?

Answer 3

hint: think of 1/x and what value of x that isn't allowed

Answer 4

In 1/x, 0 isn't allowed. So...the number of excluded values of a rational expression cannot exceed the degree of the denominator?

degree of denominator = max number of roots of the denominator = max number of excluded values
