Answer:

Yes! |-15| = 15

Step-by-step explanation:

Many people think of absolute value (the two bars symbol around the -15) as ALWAYS POSITIVE.

You can also think of absolute value as a distance. If you move 15 units, it doesn't matter in what direction you go. 15 units travelled is 15 units.

Lastly, absolute value has a V-shaped graph, that is because its always positive.

Yes, the lines on either side of the number -15 mean absolute value. Meaning that whatever number inside of the lines is positive.

What is the vertical shift for the absolute value function below. Explain how you know using complete sentences. Include the dir

koban [17]

The vertical shift of the function $f(x) = 9|x + 1| + 2$ is 2 units up

The absolute function is given as:

$f(x) = 9|x + 1| + 2$

An absolute function is represented as:

$f(x) = a|x - h| + k$

Where k represents the vertical shift.

By comparison, the value of k is:

$k = 2$

This means that the vertical shift is 2 units

Hence, the vertical shift of the function $f(x) = 9|x + 1| + 2$ is 2 units up

Geometric sequence or whatever

sladkih [1.3K]

Step-by-step explanation:

An = -2 * An-1

What this means is that you multiply -2 to the term to get the next term.

Since our 1st term (A1) is -2, we have:

A2 = -2 * A1 = -2 * (-2) = 4,

A3 = -2 * A2 = -2 * (4) = -8,

A4 = -2 * A3 = -2 * (-8) = 16,

A5 = -2 * A4 = -2 * (16) = -32,

A6 = -2 * A5 = -2 * (-32) = 64.

Hence our first 6 terms in the GP are

-2, 4, -8, 16, -32 and 64.
