Answer:

<h3>A. </h3>

Scientific notation is used to express large numbers into a smaller expression without losing important aspects of the number and its representation. Examples of large numbers are: the number of stars in a galaxy, the numbers of grain sands on a beach, the popoulation of a country.

However, the speed of a car doesn't need scientific notation, beacuse it can't be a large number.

Therefore, the right asnwer here is "Velocidad de un Carro".

<h3>B.</h3>

The given number is 0.9 \times 10^{-5}.

This number is not correct, because, according to the rules of scientific notations, the coefficient of the power must be from 1 to 9, and here we have 0.9, which is out of such interval.

<h3>C.</h3>

If we use an exponent between 0 and 1, the ten power would decrease. But, if we use exponents greater than 1, that means the ten power will increase. That's the difference between.

A. f(x) = l-2xl - 3<br> Domain: {1, 2, 3}<br> Find the range
gizmo_the_mogwai [7]

Hello there!

We are given the function:

\displaystyle \large{ f(x) =  | - 2x|  - 3} \\

To find the range, we know that domain is the set of all x-values and also called 'input' while range is the set of all y-values and also called 'output'.

Basic Function - you add the input, you get the output. You add x-value in a function, you get y-value. You add domain, you get range.

So, we substitute x = 1,2 and 3 in the function.

<u>x</u><u> </u><u>=</u><u> </u><u>1</u>

\displaystyle \large{ f(1) =  | - 2(1)|  - 3} \\   \displaystyle \large{ f(1) =  | - 2|  - 3} \\

Recall that any numbers in absolute value are always positive.

\displaystyle \large{ f(1) =  2 - 3} \\   \displaystyle \large{ f(1) =   - 1} \\

<u>x</u><u> </u><u>=</u><u> </u><u>2</u>

\displaystyle \large{ f(2) =  | - 2(2)|  - 3} \\   \displaystyle \large{ f(2) =  | - 4 |   - 3} \\   \displaystyle \large{ f(2) =  4 - 3} \\   \displaystyle \large{ f(2) =  1}

<u>x</u><u> </u><u>=</u><u> </u><u>3</u>

\displaystyle \large{ f(3) =  | - 2(3)|  - 3} \\   \displaystyle \large{ f(3) =  | - 6|   - 3} \\   \displaystyle \large{ f(3) =  6 - 3} \\   \displaystyle \large{ f(3) =  3}

Therefore, Range: {-1,1,3}

Answer:

f ( x )= ( x − 3 )( 3 x + 2 ) ( x + 1 )

Step-by-step explanation:

I believe this is the answer you were looking for.

I'm not sure what "If 3 is a zero of the function" means

But I factored the equation you provided.
