Answer:

p(3) = -38

Explanation:

p(x) = -x³ - 2x² + 7

p(3) = -3³ - 2(3)² + 7

p(3) = -27 - 2(9) + 7

p(3) = - 27 - 18 + 7

p(3) = -38

Answer:

-38.

Explanation:

p(x) = -x^3 - 2x^2 + 7

p(3) = -(3^3) - 2(3^2) + 7

p(3) = -27 - 2(9) + 7

p(3) = -27 - 18 + 7

p(3) = -45 + 7

p(3) = -38

Hope this helps!
