Let {{MATH_67}} and {{MATH_68}}. The domain of each of these functions is all real numbers. Which of the following statements are true? {{CMD_69}} {{CMD_70}}There is not enough information to determine if {{MATH_71}}.{{CMD_72}} {{CMD_73}}The functions are equal.{{CMD_74}} {{CMD_75}}If {{MATH_76}}, then {{MATH_77}}.{{CMD_78}} {{CMD_79}}We have {{MATH_80}} since {{MATH_81}} uses the variable {{MATH_82}} and {{MATH_83}} uses the variable {{MATH_84}}.{{CMD_85}} {{CMD_86}} {{CMD_87}}
