Answer:

f ( 0 ) = - 2 f ( 3 )

Step-by-step explanation:

We Have :-

f ( x ) = x³ - 5x² - 4x + 20

To Show :-

f ( 0 ) = - 2 f ( 3 )

Solution :-

f ( 0 )

( 0 )³ - 5 ( 0 )² - 4 ( 0 ) + 20

0 - 0 - 0 + 20

20

- 2 f ( 3 )

- 2 [ ( 3 )³ - 5 ( 3 )² - 4 ( 3 ) + 20 ]

- 2 [ 27 - 45 - 12 + 20 ]

- 2 ( - 10 )

20

f ( 0 ) = - 2 f ( 3 )
