    p(1/2)= 2 * (1/2)^3 - 9*(1/2) - 10

    P(1/2) = P(s) with s = 1/2

    so set s = 1/2 and 0 in your equation and evaluate it.

    Then just plug in the values 1/2 and 0 to the functions.

    okay. lets take this one step at a time P(s)=2sᶟ-9s-10 s = 1/2 P(1/2) = 2 * (1/2)^3 - 9(1/2) -10

    (1/2)^3 = 1/2*1/2*1/2 = 1/8 2(1/2)^3 = 2*1/8 = 1/4 9(1/2) = 9/2 so, P(1/2) = 1/4-9/2-10

    9/2 is nothing but 18/4 and 10 is nothing but 40/4 so, P(1/2) = 1/4 - 18/4 - 40/4 = (1-18-40)/4 = -57/4

    2(1/2)^3= how did u get 2*1/8

    what \[(1/2)^3\] its (1/2) *(1/2) *(1/2)= 1/8 but dont forget 2 2/8 = 1/4
