Question 253572: Please help me with this problem.
Look at the expression 4x-12/x^2-16. If x was replaced with 3, would the expression be considered defined? Why or why not? If x was replaced with 4, would the expression be considered defined? Why or why not? Is there another value for x that would make this expression undefined?

The rational expression is defined if the denominator is NOT equal to zero, undefined otherwise.
