Question it 7 Use the intermediate valve theorem to show that the polynomial has a red zero between the given integers . f ( x ) = 4 x 3 - 2 x - 4 " between I and 4 ( f ) ( f ) Evaluate f( ) f ( 1 ) = 4 ( 1 ) - 2(1 ) - 4 f f 4 - 2 - 4 4 - 6 = 1 - 2 Now Evaluate f ( 4 ) f ( 4 ) = 4 ( 4 ) 3 - 2 ( 4 ) - 4 ( f ) 256 -8 -4 - 12 24 4 Since f ( 1 ) = - 2
