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.
It is a equation
Because it has an equal sign if it does not it will be a expression.
x = 14
I am sure of the answer :)
