Explanation:

We have: p(x) = x^(3) + 2 x^(2) + 3 x + 4; c = - 1

First, let's substitute x with c:

=> p(c) = (c)^(3) + 2 (c)^(2) + 3 (c) + 4

Then, the value of c is given as - 1.

Let's substitute c with - 1:

=> p(- 1) = (- 1)^(3) + 2 (- 1)^(2) + 3 (- 1) + 4

=> p(- 1) = - 1 + 2 - 3 + 4

=> p(- 1) = 1 + 1

=> p(- 1) = 2
