When you find f(2) for a given function f, you are finding the y value associated with x= 2

sveticcg [70]

Answer:

The provided statement is TRUE.

Step-by-step explanation:

The function <em>f</em> is an expression in variable <em>x</em>.

The entire expression can either be denoted by f (x) or <em>y</em>.

For instance consider the quadratic expression:

f (x) = ax² + bx + c

≡ y = ax² + bx + c

So, on computing the value of f (2), it implies that we are computing the value of y for <em>x</em> = 2.

Thus, the provided statement is TRUE.

Math 2 Homework Mod 2.1 (Day 2) Absolute Value Functions

Semenov [28]

The descriptions of the transformations are:

Vertex: (-6, 0)
Stretch factor: 2
Domain: set of all real numbers
Range: set of real numbers greater than or equal to 0

<h3>How to describe transformations, graph, and state domain & range using any notation?</h3>

The function is given as:

f(x) = -2|x + 6|

The above function is an absolute value function, and an absolute value function is represented as:

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

Where

Vertex = (h, k)

Scale factor = a

So, we have:

a = -2

(h, k) = (-6, 0)

There is no restriction to the input values.

So, the domain is the set of all real numbers

The y value in (h, k) = (-6, 0) is 0

i.e.

y = 0

Because the factor is negative (-2), then the vertex is a minimum

So, the range is all set of real numbers greater than or equal to 0

Hence, the descriptions of the transformations are:

Vertex: (-6, 0)
Stretch factor: 2
Domain: set of all real numbers
Range: set of real numbers greater than or equal to 0

Explain how to write 1.25 times 10 to the negative third power in standard form

OleMash [197]

This is called "Scientific Notation"

$1.25 \times {10}^{ - 3}$
So you will always see the 10... Don't worry about it but worry if it is negative or positive because the sign will determine how to move the decimal point.

So, since it is negative then we will be moving the decimal point to the left. And, if it was a positive 3 then we'd move the decimal point to the right!

We will be moving it to the left "3" times because it says - 3 not - 5, etc...
$1.25 \times {10}^{ - 3} = 0.00125$
So just move the decimal 3 times in this case and there you go, your standard form. I forgot what the other form is but I can still solve for it...

I hope this helped if you have any questions then feel free to ask!!

Which angles are corresponding angles?

Katena32 [7]

Corresponding angles are defined as angles that are on the same side of the transversal (given the lines are parallel, which they are) and are on the same side of the parallel lines. Choices D, E, and F are angles on the same side of the transversal and on the same side of the parallel lines.
