Provide an appropriate response.The cost C of processing exhaust gases so that you remove all but x percent of the pollutants is given by 
Find the values of x for which C < 0. Discuss the meaning of the results.
What will be an ideal response?
C < 0 for x > 100 or x < 0. Neither one of these answers makes sense because the amount of pollutants can't be more than 100% or less than 0%.
