Answer:
B
Step-by-step explanation:
For the function f(x) = x^2 + 2x - c to have integer zeros it must factor. Substitute c for the values listed below and see which options factor.
A. 2
f(x) = x^2 + 2x - 2 does not factor
B. 3
f(x) = x^2 + 2x - 3 does factor into (x + 3)(x - 1) so the zeros would be x = -3, 1
C. 4
f(x) = x^2 + 2x - 4 does not factor
D. 6
f(x) = x^2 + 2x - 6 does not factor
