Answer 2

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

$\huge\pink{\boxed{\blue{\mathcal{\overbrace{\underbrace{\fcolorbox{blue}{aqua}{\underline{{answer}}}}}}}}}$

p(x) = 2x−2x³+7

p(−1)=2×(−1)−2×(−1)³ +7

==> −2−2×(−1)+7

==> −2+2+7

==> 7

Thus, the value of polynomial for x=−1 is 7
