How do you solve this quadratic equation by completing the square?

The answer would be 2 +/- √-2

Step-by-step explanation:

In order to complete the square, we have to start by getting all of the constants to the right side.

k^2 - 4k + 1 = -5

k^2 - 4k = -6

Now we need to take the k coefficient (-4) and cut it in half (-2). Now we square that number (4) and add it to both sides

k^2 - 4k + 4 = -6 + 4

k^2 - 4k + 4 = -2

Now we can factor the left side and solve.

(k - 2)^2 = -2 > take the square root of both sides

k - 2 = +/- √-2

k = 2 +/- √-2

Reflect across the y-axis, stretch the graph vertically by a factor of 3

Step-by-step explanation:

The question has certain errors, in fact the functions are the following:

g (x) = 3 * (2) ^ - x

f (x) = 2 ^ x

The transformation that we can do to obtain the translated graph, Are given in 2 steps, which are the following:

1. When x is replaced by -x, then it reflects the graph on the y axis.

2. 3 multiplies with the function, it means that it stretches the main function vertically in 3 units.

So to summarize it would be: Reflect across the y-axis, stretch the graph vertically by a factor of 3
