Find the value of the polynomial 5x3 - 3x2 - 7x + 11 at x = 1​

p(x) = 5x^3-3x^2-7x+11

i) p(0) = 5(0)^3-3(0)^2-7(0)+11

        = 0-0-0+11

        = +11

ii) p(1) = 5(1)^3-3(1)^2-7(1)+11

        = 5-3-7+11

        = 16-10

        = 6

iii) p(-1) = 5(-1)^3-3(-1)^2-7(-1)+11

          =  -5-3+7+11

           = -8+18

           = +10

iv) p(2) = 5(2)^3-3(2)^2-7(2)+11

          = 5(8)-3(4)-14+11

          = 40-10-14+11

          = 50-24

          =  26
