We now consider an inequality of the formf1（x）>f2（x）.Every numerical value x0 taken from the domain ofadmissible values is called a solution of theinequality,if,when x0 is substituted into both sidesof the inequality,the result is a true numericalinequality.All the solutions of an inequalityconstitute the solution set of the inequality.Forinstance,the inequality x2<1 has for its solution setthe open interval（-1,1）.Sometimes,for the sakeof brevity,we loosely say that the solution of
We now consider an inequality of the form
f1（x） 〉f2（x）.
Every numerical value x0 taken from the domain of admissible values is called a solution of the inequality, if, when x0 is substituted into both sides of the inequality, the result is a true numerical inequality. constitute All the the solution solutions of an inequality set of the inequality.
