find the cubic function fx given the zeros f1 0 f18Solution

find the cubic function f(x) given the zeros; f(-1) =0, f(1)=8

Assuming you mean 3, -4, 6 If they are zeros then x - 3 = x + 4 = x - 6 = 0 i.e. (x - 3)(x + 4)(x - 6) = 0 or x^3 - 5 x^2 - 18 x + 72 = 0 On the other hand If you meant 1.3, -4, 6 If they are zeros then x - 1.3 = x + 4 = x - 6 = 0 i.e. (x - 1.3)(x + 4)(x - 6) = 0 or x^3 - 3.3 x^2 - 21.4 x + 31.2 = 0
