Answer:

False

Step-by-step explanation:

Look at the inputs (x-values)

If the inputs are the same, the relationship is <u><em>Not</em></u> a function.

Inputs (x-values), cannot share the same output (y-values).

Example:

<u>Inputs</u>      <u>Outputs</u>

3              2    

2              5

8              5

3              6

In the input there are two 3's which causes this to not be a function.

(Outputs can have the same numbers repeating just not inputs.)

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.
