**Answer:**

The range is −5≤y≤−1 - 5 ≤ y ≤ - 1 .

**Answer:**

Option **A** is correct.

**Step-by-step explanation:**

We need to find the difference of two matrices.

The matrices are:

We will subtract each row entry of Matrix 1 from the corresponding row entry of Matrix 2.

So, We get the answer

which matches Option A.

So, Option **A** is correct.

Answer:

(fg)(x) = (4x^2 + x^4)(x^2 + 4)^(1/2)

Step-by-step explanation:

Mathematically;

(fg)(x) = f(x) * g(x)

so we have;

4x^2 +x^4 * √(x^2 + 4)

But √(x^2 + 4) = (x^2 + 4)^(1/2)

So we have;

(fg)(x) = (4x^2 + x^4)(x^2 + 4)^(1/2)
