Determine whether the polynomial \( f(x) = - (x - 2)^2(x + 4) \) is positive or negative over each interval. **Hint:** For each part, find a number in the given interval and plug it into the function. You do not have to multiply the function out to do this. - On \( x < -4 \), \( f(x) \) is **Negative** - On \( -4 < x < 2 \), \( f(x) \) is **Negative** - On \( x > 2 \), \( f(x) \) is **Positive**
