olchik [2.2K]3 years ago

Answer:

i do not agree

Step-by-step explanation:

you see, 41 IS smaller than 21, but that does not mean that -14 is smaller than -21.

when you add positive numbers, the numbers get larger and when you subtract them they get smaller.

but the opposite is true of negative munbers. when you add with negative munbers the number behind the dash gets smaller while with adding with negative numbers it gets bigger.

basicaly, forget everything i just said and realise that with negative numbers the smaller numbers are actually bigger and vice versa.

Which statement is true of the function f(x) = -3/x? Select three options.
melamori03 [73]
<h2>Answer:</h2>

We have the following function:

f(x)=-\frac{3}{x}

The graph of this function has been plotted below. So lets analyze each statement:

<h3>1. The function is always increasing. </h3><h3>False</h3>

As you can see x increases from -∞ to 0 and decreases from 0 to +∞

<h3>2. The function has a domain of all real numbers. </h3><h3>False</h3>

The function is undefined for x=0 since x is in the denominator.

<h3>3. The function has a range of {yl- </h3>

Statement is unclear but the range is the set of all real numbers except zero.

<h3 /><h3>4. The function is a reflection of y = 3. </h3><h3>False</h3>

The function is a reflection in the x axis of the function g(x)=\frac{3}{x}

<h3>5. The function passes through the point (3,-27).</h3><h3>False</h3>

This is false since:

f(3)=-1\neq -27

Note. As you can see those statements are false, so any of them is true, except item 3 that is unclear.

VERY IMPORTANT!! PLEASE ANSWER CORRECTLY!!
jolli1 [7]

Answer:

x^2-4x+8

x^2+4

x^2+2x+2

Step-by-step explanation:

(1) (x-2+2i) (x-2-2i)

Multiply each term inside second parenthesis

x^2-2x-2ix -2x+4+4i+2ix-4i-4i^2

Combine like terms. the value of i^2=-1

x^2-4x+4-4(-1)

x^2-4x+8

(2) (x+2i)(x-2i)

x^2- 2ix +2ix -4i^2

Replace i^2 by -1  

x^2+4

(3) (x+1+i)(x+1-i)

Multiply each term inside second parenthesis

x^2+x-ix+x+1-i+ix+i-i^2

Combine like terms. the value of i^2=-1

x^2-4x+4-4(-1)

x^2+2x+2
