We now consider an inequality of the formf_1(x)>f_2(x).Every numerical value x_0 taken from the domain ofadmissible values is called a solution of theinequality,if,when x_0 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 x~2<1 has for its solution setthe open interval(-1,1).Sometimes,for the sakeof brevity,we loosely say that the solution of the
We now consider an inequality of the formf_1 (x)> f_2 (x). Every value value x_0 taken from the domain ofadmissible values is called a solution of the inequality values, if, when x_0 is substituted into both sides of the inequality, the result is a true numericalinequality.All the solutions of an inequalityconstitute the solution set of the inequality. Forinstance, the inequality x ~ 2 <1 has for its solution set the open interval (-1,1) .Sometimes, for the sakeof brevity, we loosely say that the solution of the
