I need help on questions 8-11. I don't seem to understand them.

8 .Find the smallest possible degree of a polynomial with thegiven graph . Explain your reasoning .The smallest possible degree isbecausethe graph hasX - intercepts andturning points9 . Divide by synthetic division .2 X 3 - 9 X 2 + 2 X + 8x + .2 X - 9 X 2 + 2X + 8\Remainder+ X10 . Use synthetic division and the Remainder Theorem to find each function value . Check your answer by evaluating thefunction at the given x- value .F ( X ) = X* + 7X 2 + 9\2 . 4 ( 1 )b . f ( - 1 )c . 4 / 5)d . $ ( 10 )2 . 4 ( 1 ) =( Type an integer or a simplified fraction . )b . f ( - 1 ) =( Type an integer or a simplified fraction . ). ` ( 2 ) =( Type an integer or a simplified fraction . )d . f ( 10 ) =( Type an integer or a simplified fraction . )17 .
