Answer:

The correct options is Experimental Study for both the answer.

Explanation:

Experimental study is a method of research that is used in order to test the implications of a product or a hypothesis.

In both the questions above, Experimental study is used because they are testing products like healing medicine and a fire suite. hey need to go through the experimental phase in order to see the implications of their product either successful or unsuccessful. That helps them to know what is missing and make it better.

Given f(x) = x^2 − 2x − 5.

lukranit [14]

Answer:

$(x - 1)^2 - 6$

Step-by-step explanation:

You need to know:

Vertex form = $a(x -h)^2 + k$

The vertex is at

(h, k)

<u>Need to know about perfect squares </u>

<u>Need to know how to complete the square.</u>

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

<u>To convert $x^2-2x-5$ you need to complete the square on the equation.</u>

Complete the Square $x^2 - 2x -5$

$x^2 - 2x -5$

$(x^2 - 2x) -5$

Divide -2 by 2 and then square it.

$\frac{-2}{2} = -1$

$-1^2 = 1$

Add the one to the parentheses and subtract the one from the 5

$(x^2 - 2x +1) -5 -1$

Square $(x^2 - 2x +1)$

$(x-1)^2$

Now we have

$(x - 1)^2 -5 -1$

<u>Next add</u> -5 - 1 = -6

$(x - 1)^2 - 6$

Our quadratic is in vertex form now.

Vertex form = $a(x -h)^2 + k$

our equation = $(x - 1)^2 - 6$

Vertex = (1, -6)

Step-by-step explanation:

Hello!

The graph linked above is what is known as a "Reciprocal Graph"

A reciprocal in math is a multiplicative inverse or reciprocal for a number x.

For example the reciprocal of 1/2 is:

$\frac{1}{2} = \frac{2}{1}$

With this in mind we know that our graph will have the function $\frac{Some.number}{x}$

Shown below is the graph of $\frac{6}{x}$
