Evaluate and simplify completely i) ) 2 ( - g = -1 ii) ) 0 ( g = -3 iii) ) 1 ( g = undefined iv) ) 4 ( g = 1 v) ) 3 ( + x g = 2 3 + x b. Solve algebraically for exact x i) 5 ) ( = x g ii) 4 ) 2 ( = + x g iii) 4 2 ) ( = + x g x = 5 8 x = 25 . 0 - x = 5.2 2. Simply the difference quotient for the following functions [different quotient ( 29 ( 29 h x f h x f - + ] a) ( 29 3 2 2 + + = x x x f ( 29 ( 29 h x f h x f - + = h x + + 2 2 b) ( 29 5 3 - = x x f ( 29 ( 29 h x f h x f - + = 2 2 3 3 h x xh + + c) ( 29 x x f 4 = ( 29 ( 29 h x f h x f - + = ) ( 4 h x x + - 3. Simplify the following completely with a common denominator. Your final answer will not contain any negative exponents. a) x x x x 2 2 5 1 4 + - - = ( 29 1 2 2 3 3 2 - + + x x x x b) ( 29 ( 29 2 4 2 2 - + + x x b b = ( 29 2 3 2 1 - + x b or ( 29 ( 29 x b b 3 2 2 2 + + c) 3 2 3 2 1 + + + + t
