Question

evaluate the polynomial function for the given values of
$p(x) = 2x^3 - 5x + 7$; $p(4)$, $p(-2)$, and $p(0)$
$p(4) = 19$ (simplify your answer.)
$p(-2) = \square$ (simplify your answer.)

Explanation:

Step1: Substitute $x=-2$ into $P(x)$

$P(-2)=2(-2)^2 -5(-2)+7$

Step2: Calculate exponents and multiplications

$P(-2)=2(4) +10 +7$

Step3: Compute final sum

$P(-2)=8 +10 +7$

Answer:

$P(-2)=25$
