Question

Please help me i am so lost :(

Answer 1

Let's evaluate the value of given polynomial function, at x = -2

that is p(-2) :

• 
  `5 {x}^(3) + 8 {x}^(2) - 3x + 1`

• 
  `5( - 2) {}^(3) + 8( - 2) {}^(2) - 3( - 2) + 1`

• 
  `(5 * ( - 8)) + (8 * 4) - ( - 6) + 1`

• 
  `- 40 + 32 + 6 + 1`

• 
  `39 - 40`

• 
  `- 1`

Hence, correct option is B. p(-2) = -1
