Q. QuestionFor which values of x is the expression undefined?3x+8x−9AnswerAttempt 1 out of 3
Set Denominator Equal to Zero: Set the denominator equal to zero and solve for x.3x+8=0
Subtract and Solve for x: Subtract 8 from both sides of the equation.3x+8−8=0−83x=−8
Divide to Isolate x: Divide both sides by 3 to isolate x.33x=3−8x=3−8
Expression is Undefined: We have found the value of x that makes the denominator zero, which means the expression is undefined for this value of x.x=−38
