Answer:

f(x) = x^3 + 4x^2 - 7x - 28

Step-by-step explanation:

If the roots of this cubic function are Square root of seven,  -Square root of seven,  -4, then the factors must be (x^2 - 7)(x + 4).

Multiplying this out, we get f(x) = x^3 + 4x^2 - 7x - 28.

Note:  Please use " ^ " to indicate exponentiation.
