$\sf \bf \huge {\boxed {\mathbb {QUESTION}}}$

$\sf \bf If \:k=2,\:Find \:the \:value\: of\: p(k)= 1-{k}^{2}+2{k}^{3}$

$\sf \bf \huge {\boxed {\mathbb {ANSWER}}}$

$\sf \bf \huge\underline {k=2}$

$\sf \bf \implies {p(k)= 1-{k}^{2}+2{k}^{3}}$

$\sf \bf \implies {p(2)= 1-{(2)}^{2}+2{(2)}^{3}}$

$\sf \bf \implies {p(2)=1-4+2(8)}$

$\sf \bf \implies {p(2)=-3+16}$

$\implies{\boxed{\color {green} {\sf \bf p(2)=13}}}$
