Question

The excluded values of a rational expression are 2 and 5. Which of the following could be this expression?

Answer 1

Answer: d on eng

Explanation:

Answer 2

A value will be excluded from a rational expression if it causes the denominator to be zero as dividing by zero is undefined.

An example that would work for your specific question is:


`y = ((x - 3)(x-1))/((x-2)(x-5))`

If you plug in either 2 or 5 into this equation the denominator will be zero causing the expression to undefined there, so the values 2 and 5 are excluded from the domain of the expression.
