Question

Is p(x)=2x^3-2x^2-3x+5 , then P(-1) is.

1) 7
2) 8
3) 9
4) 10

please give the correct answer

​

Answer 1

Step-by-step explanation:

p(x) = 2x³ - 2x² - 3x + 5

=> p(-1) = 2(-1)³ - 2(-1)² - 3(-1) + 5

=> 2(-1) - 2(1) - 3(-1) + 5

=> - 2 - 2 + 3 + 5

=> - 4 + 8

=> 4

if p(x) = 2x³ + 2x² - 3x + 5, then

p(-1) = 2(-1)³ + 2(-1)² - 3(-1) + 5

=> -2 +2 + 3 + 5

=> 8
