Fill in the blank by performing the indicated elementary row operation(s).
Scilla [17]

In this question, we are given a matrix, and we have to perform the given operation.

The matrix is:

\left[\begin{array}{ccc}6&-1&|5\\1&-5&|0\end{array}\right]

The following operation is given:

R_1 \rightarrow -6R_2 + R_1

In which R_1 is the element at the first line and R_2 is the element at the second line.

Updating the first line:

R_{1,1} = -6*1 + 6 = 0

R_{1,2} = -6*-5 - 1 = 30 - 1 = 29

R_{1,3} = -6*0 + 5 = 5

Thus, the filled matrix will be given by:

\left[\begin{array}{ccc}0&29&|5\\1&-5&|0\end{array}\right]

<h3>Answer: Choice D.  g(x) = 3|x-3| - 6</h3>

======================================================

Explanation:

Points are of the form (x,y), where y = f(x) since y and f(x) are outputs.

When we vertically stretch by a factor of 3, we are making the function curve 3 times more stretched out along the vertical y axis. So a general point (x,y) becomes (x,3y). Whatever the y coordinate is, we multiply by 3 to get its stretched out counterpart.

Eg: (0,-2) on f(x) moves to (0,-6) which is on g(x)

-------------

Since y = f(x), and we're multiplying y by 3, we can say

f(x) = |x-3| - 2

3*f(x) = 3*( |x-3| - 2 )

3*f(x) = 3|x-3| + 3(-2)

3*f(x) = 3|x-3| - 6

g(x) = 3|x-3| - 6
