To find the zeros of the function \( y = 3(x+2)(x-1)(x+4) \), we need to set the function equal to zero:
\[
3(x+2)(x-1)(x+4) = 0
\]
Since 3 is a constant and does not affect the zeros, we can simplify our task to finding when the product of the factors is equal to zero:
\[
(x+2)(x-1)(x+4) = 0
\]
Now we set each factor equal to zero:
1. \( x + 2 = 0 \) ⇒ \( x = -2 \)
2. \( x - 1 = 0 \) ⇒ \( x = 1 \)
3. \( x + 4 = 0 \) ⇒ \( x = -4 \)
Thus, the zeros of the function are:
- \( x = -2 \)
- \( x = 1 \)
- \( x = -4 \)
Now, let's identify these zeros from the options provided:
A. 1
B. -1
C. 2
D. -2
E. 3
F. -3
G. 4
H. -4
The correct responses for the zeros of the function are:
- **D: -2**
- **A: 1**
- **H: -4**
So the zeros of the function are **D, A,** and **H**.

3(x+2)(x-1)(x+4) = 0
