question 3 points 1

find \\(-f\\) for the given matrix.

\\(f = \

$$\begin{bmatrix} 20 & -6 & -42 & 22 \\end{bmatrix}$$

\\)

\\(\bigcirc \

$$\begin{bmatrix} -20 & 6 & 42 & -22 \\end{bmatrix}$$

\\)

\\(\bigcirc \

$$\begin{bmatrix} -10 & 6 & 22 & -12 \\end{bmatrix}$$

\\)

Explanation:

Identify the given matrix

Using the Scalar Multiplication knowledge point

$$ F =
LATEXBLOCK0
$$

Apply scalar multiplication by -1

Using the Scalar Multiplication knowledge point

$$ -F = -1 \cdot
LATEXBLOCK1
=
LATEXBLOCK2
$$

Answer:

• (A) \([-20 \quad 6 \quad 42 \quad -22]\) (Correct answer)
• (B) \([-10 \quad 6 \quad 22 \quad -12]\)
