Question

If p(x) = 5x – 2x 2 – 3, evaluate p(0) + p(1) – p(-2).

Answer 1

Answer:

= 18

Step-by-step explanation:

$p(x)=5x-2x^2-3 \\\\ =>p(0)=5(0)-2(0)^2-3 \\ p(0)=0-0-3\\p(0)=-3 \\\\ =>p(1)=5(1)-2(1)^2-3 \\p(1)=5-2-3 \\ p(1)=3-3\\p(1)=0 \\\\ => p(-2)=5(-2)-2(-2)^2-3\\p(-2)=-10-2(4)-3\\p(-2)=-10-8-3\\p(-2)=-21 \\\\ \implies p(0)+p(1)-p(-2) \\ =-3+0-[-21]\\=-3+21\\=18$
