Answer:

  • P(1) = -3
  • P(-1) = -15
  • P(-2) = -57

Step-by-step explanation:

P(x) = 5x³-2x²+x-7 is the required equation

P(1) = 5(1)³-2(1)²+(1)-7

       = 5-2+1-7

       = -3

P(-1) = 5(-1)³-2(-1)²+(-1)-7

        = -5-2-1-7

        = -15

P(-2) = 5(-2)³-2(-2)²+(-2)-7

        = (5×-8)-(2×4)-2-7

        = -40-8-2-7

        = -57

Hope It Helps You !!!!!
