Question

Find the indicated value of the polynomial. Match your result to the correct answer below.

P(x) = x4 + x3 - x2 - x + 1, P(-1)
Select one:
a.
1
b.
3
c.
0
d.
5

Answer 1

To find the indicated value of the polynomial P( x) at P(- 1), we substitute-1 into the equation and simplify to find that P(- 1) = 1, which matches answer choice( a).

Step-by-step explanation:

To find the indicated value of the polynomial P( x) for P(- 1), we substitute-1 into the equation P( x) = x4 x3- x2- x 1

P(- 1) = (- 1) 4(- 1) 3-(- 1) 2-(- 1) 1

P(- 1) = 1- 1- 1 1 1

P(- 1) = 1

thus, the correct answer isa. 1.
