Answer:

17

Step-by-step explanation:

p (x) = x^4 + 3x^3 - 16x^2 + 2x - 7

p (3) = (3)^4 + 3(3)^3 - 16(3)^2 + 2(3) - 7

p (3) = 81 + 81 - 144 + 6 - 7

p (3) = 17

I hope this helps

Answer:

Answer:

P(3)=-58

Step-by-step explanation:

P(x) = (3) + 3(3)³ - 16(3)² 2(3) -

P(x) = 12 + 27- 96 - 1

P(x) = 39-97

P(x) = -58
