Answer:
third option
Explanation:
Given x = a and x = b are zeros of f(x), then
(x - a) and (x - b) are factors of f(x) and f(x) is the product of the factors
f(x) = (x - a)(x - b)
Given the zeros are x = - 3, x = 0 and x = 4 , then
(x - (- 3) ), (x - 0), (x - 4) are factors, that is
(x + 3), x, (x - 4) , so
f(x) = x(x + 3)(x - 4)
