I'm assuming that the expression is %282%29%2F%283w%2B4%29


%282%29%2F%283w%2B4%29 Start with the given expression


3w%2B4=0 Set the denominator equal to zero. Remember, dividing by 0 is undefined. So if we find values of w that make the denominator zero, then these values will make the expression undefined.


3w=0-4Subtract 4 from both sides


3w=-4 Combine like terms on the right side


w=%28-4%29%2F%283%29 Divide both sides by 3 to isolate w



w=-4%2F3 Reduce


=======================================================

Answer:

So if w=-4%2F3, then the expression %282%29%2F%283w%2B4%29 is undefined.
