Final answer:
To find the zero(s) of the function, factor the quadratic equation (c + 3)(c + 4) = 0 to get c = -3 or c = -4.
Step-by-step explanation:
To find the zero(s) of the function f(c) = c² + 7c + 12, we need to solve the quadratic equation by factoring or using the quadratic formula. In this case, the quadratic equation can be factored as (c + 3)(c + 4) = 0. This means that the function will equal zero when c = -3 or c = -4.
