Answer 2

$\LARGE\textbf{\underline{\underline{Answers :-}}}$

• $\large\textbf{p( x ) = 5 - 4x + 2x^{3} }$

__________________________________

• $\large\textsf{ p( 0 ) = 5 - ( 4 × 0 ) + 2 × 0^{3} }$

• $\large\textsf{= 5 - 0 + 0}$

• $\large\boxed{\therefore\textbf{p( 0 ) = 5}}$

___________________________________

• $\large\textsf{p( 3 ) = 5 - ( 4 × 3 ) + 2 × 3^{3} }$

• $\large\textsf{ = 5 - 12 + ( 2 × 27 )}$

• $\large\textsf{= 5 - 12 + 54}$

• $\large\boxed{\therefore\textbf{p( 3 ) = 47}}$
