    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 !!!!!
